Sydney Audio Club Meeting - Sunday 18th November 2018 - Lenehan Audio

Recommended Posts

Our November club meeting is the last Sydney Audio Club for this calendar year.  (We’ll be back January 20th 2019.)  


For our November club meeting we are very pleased to have Mike Lenehan of Lenehan Audio return after quite a few years.  Mike last presented to the club back in March 2012…!!  He’s been keen to come back but he was just too busy to return earlier!  Busy is good – his business is thriving.  


Anyone that knows Mike will know he is meticulous in his designs and build – he won’t release a product until the design is perfect and the product is of very high quality.  And yet somehow he still finds the time to be very active and helpful in forums.  He is a great Aussie talent and we’re happy to have him back.


Detail of the system…


Lenehan ML2 Reference speakers with dedicated stands.  Refer to http://www.lenehanaudio.com.au/ml2-ref.html.  “The ML2 is the next generation of high-end two way monitors from Lenehan Audio. Designed for absolute no compromise music systems.”  Uses Dueland caps and resistors in cross-over (also sold separately through his website).  35 - 25Khz +/- 1.5db response in room.


Heschl Audio Labs integrated amp.  Don’t bother Googling this one… it’s so new that there’s nothing to be found!  The good news is that it’s Aussie, well designed and built … and 300wpc.  Designed and built by Ron Harris.


FoilFlex interconnects and loudspeaker cables.  These are new cables designed by Lenehan Audio. 


Isolation platforms for the electronics.  Also designed by Lenehan Audio.


3Hz Isolation platforms for the speakers.  Also designed by Lenehan Audio.


Curious USB cable.  Famous giant-killer USB cable sold by Lenehan Audio.  Made by Rob Woodland in Queensland.


Mike’s source for his presentation will be his laptop with the Audirvana Plus music player.


Our source for our BYO session will be an Oppo BDP-105D multi-format player. 


The second half of the music sessions will be our popular BYO.   Members and guests are welcome to offer music to share with us all.  So bring along your favourite music on CD or USB thumb/flash drives (sorry, no vinyl this month).  All we ask is that the music and recordings be interesting.  We'll ask you to tell us a little about the artist/recording before it is played.  Tracks over 6 minutes will be faded out, to give everyone a fair go. 


Whether you are a novice or a seasoned veteran, you will have the opportunity to listen, learn and share your experiences with others.  Feel free to come and hear the capabilities of the system, or to just share the experience with like-minded music lovers in a friendly and relaxed atmosphere.  


Guests are welcome – we are a very friendly club so you don't need to know anyone to join us for an afternoon of fine music and sound.


Venue:  Epping Creative Centre, Dence Park
Address:  26 Stanley Road, Epping 

When:  Sunday 18th November 2018

Doors open 1pm
Meeting starts at 2pm
Best regards,

Our November meeting was well attended.  It was a fun day with lots of good food, good music, a superb system and great company.  We had lots of people indulging in the BBQ (as did I!), and things were really humming by around 1:30. 


At 2:00 we managed to get most people into the room for our AGM.  Again, this was a short affair whereby George dissolved the committee and then read out all the nominations for the Committee roles.  All were voted in collectively.  Our bank financial statement for the year ending June 30th 2018 was also approved.  For the record, the Committee has Andrew Baldwin (no official title), David Minarik as our Public Officer, George Davidson as Vice- President, Keith Morris as Treasurer, Stephanos Eliades as Secretary, Steven Polley as Events Coordinator, Paul Bryant as Technical Advisor (and Facebook support) and Tom Waters as President.  We are also ably supported by Ray Eade who looks after our website.


I then introduced our main presenter for the day.  Mike Lenehan really needs little introduction – he’s well known and respected in the industry, and well known to members and guests alike.  Mike brought in his ML2 Reference speakers.  His speakers weighed in at 32Kgs each, and each stand was 54Kgs.  The speakers were a gorgeous burnt orange colour (well, I liked them if no one else did!) in an automotive paint finish.  The ML2 Reference are not huge stand mount speakers, but were quite capable of driving considerable volume into the room.  Their power handling is very high, and the Heschl Audio integrated amplifier was happy to oblige with loads of power and current.  It delivered 350 wpc into 8ohms, 600 wpc into 4ohms.  The amp was 45Kgs or so in weight – heavy but not overly so, nevertheless it certainly delivered in sound quality.  We were fortunate to have the designer, Rod Harris, attend the meeting.  Both Mike and Rod gave talks about their products, and there were heaps of questions for both.


Mike also conducted some A-B-A comparisons where he played music with his Macbook sitting on the table top, and then sitting on the 3Hz Isolation platform.  From the back of the room, I thought Dean Martin’s voice sounded better on the isolation platform.  It didn’t hit you in the face, but I thought the midrange became more clear and open and the spittle on Dean’s lips seemed more apparent when he sang.  Many noted that the bass seemed a bit tighter.  Mike said that these devices are considerably more effective under the speakers (he’s tried it).  The problem is that they are too unstable with the weight and height of speakers on them.  He’s working on a version for speakers that can be safely marketed (read ... less tipsy!).


I thought the ML2 Reference speakers driven by Rod’s amp sounded very good in our tricky room.  Unfortunately though, when we had our BYO session we couldn’t get the built-in DAC in the integrated amp to lock onto the Oppo.  We weren’t sure where to level the blame for that because we didn’t have the time to pursue it further.  So instead of using the Oppo as just a transport, we had to use it with its analog outputs into the integrated amp – the sound quality suffered as a consequence.  The sound was much better through Mike's Macbook running Audirvana with a Curious USB cable link (also sold by Mike) into the DAC section of the integrated amp. Mike’s music presentation was universally considered better.


Here is some feedback lifted from our Feedback forms….


“Great discussion and presentation.  Very interesting.  Great food!”


“Speakers and amplification excellent - let down by Oppo.  Speakers can be very critical of poor recordings.”


“Most of what was said was a foreign language, but I'm sure those who knew the language enjoyed it immensely!”


“Very interesting discussion re: the resonance platform, copper screws and design parameters behind the amplifier.”


“Very interesting - particularly the discussions.  Technical expertise helped.  The A-B-A comparison was good.”


“Great meeting to finish the year.  Lenehan speakers were impressive.  Amplifier is another great Aussie product.”


“Very good mix of product design and demonstration.  Very good prototype of the amplifier.  Cabling was an excellent locally designed and made product.”


“Great festive atmosphere, great BBQ - thanks George!  Streaming audio sounded much better.  Very impressive amplifier although not cheap.  Speakers looked and sounded great, huge soundstage.”


“Always enjoyable EOY BBQ and GTG.  Pleased to see and hear Aussie HiFi builders.  Once again high quality sound from bookshelf/stand mount speakers.  Don't need multi-driver and/or large floorstanders for good sound.”


“Great first half chat/info session.”


“Great BBQ and salads.  Lovely speakers and amp.”


“Good design principals in amplifier.”


“Talk was very interesting in relation to resonances and vibration.  Speakers and amp sounded great with good recordings.”

Hi Tom.      Thanks again for the invitation ! Big weekend and a great meeting. 

There were a few good tricky questions also ! I needed around 45minutes though to answer each one 😱 

Your membership has a good knowledge base so I felt stuff was being understood !  Was it really 6 years since I was there last ? Seems like 1 year .                Best Regards.   Mike Lenehan

      *Slight colour variation on 1 woofer , Spoke To Mike Lenehan and said nothing to worry about but if you wanted a new one would be $175 from Mike, Works perfectly I am guessing initial owner had in sunlight maybe. Grills never used in wrappers still and might need magnets but in new packaging and mint condition. Again Mike will fix up if required.

      Price: $ Item Condition: Used Shipping Options: Pickup is available,Audition is not available, but in-person pickup can be arranged with limited personal contact Suburb or Town: Sutherland State: New South Wales Payment Method: Reason for selling: Item:  Lenehan ML2 Satori Prototype
      Location: Southern Sydney ( 2232 )
      Price:  4.2k - happy to courier at buyers expense but prefer local pick up
      Item Condition: 9/10, cannot find any blemishes, but are 'used'
      Reason for selling: NLR
      Payment Method: Pickup - Cash, Paypal, COD Only
      Extra Info:
      Selling my ML2 Satori standmount speaker.  Just over a year old, delivered to me in December 2018.
      Instead of the usual 6.5 inch woofer, these have a 7.5 inch Satori MW-19P papyrus woofer.  They are the prototype of a new line that Mike was working on.  He just wasn't sure to go ahead as these woofers cost nearly three times as much as the HDS Nomax he currently uses, so the cost would have to be passed along to the customers.  He said when I was talking about purchasing them that they will sound better than the current ML2 speakers including the Reference with the current crossover.  He said it wouldn't beat the ML2 Limiteds.  I cannot say whether it does or doesn't as I have only ever heard the ML2 Satoris.   They do sound great.
      These speakers weigh in a couple more kilos at 35 and are a bit deeper than usual.  4 cm deeper from memory, this is due to getting the frequency response lower than the normal ML2 and they are also more sensitive at 88. 
      Will post a picture of the crossover this evening.

      The ML3 was designed with one specific goal in mind: 

      Reproduce the input signal better than any Loudspeaker currently in production. 

      The task is Herculean of course and we are very well aware of many other such attempts both present and in the past. What size room will this Loudspeaker be built for? 

      There is no doubt that an 8inch two way will drive a room of reasonable dimensions only! We're talking here of around 140 cubic mtrs | 5000 cubic feet with dimensions approximately 6mtrs x 8mtrs x 3mtrs. This is certainly a decent size living room. Due mainly to it’s PRC Xover and bottom vent design, the ML3 will drive a room as small as 50 cubic mtrs | 1700 cubic feet with no bass boom whatsoever! 

      OK, but how much energy can an 8 inch two way produce? I mean, will they have enough steam in the bass for me? After all sometimes when I’m in the mood I like to get into some Rage Against the Machine or Tool or even Faithless. But at the same time I mostly listen at moderate levels to Jazz and Classical music. 

      ML3’s have, we believe; state of the art bass reproduction. Rock solid into the mid 20hz region, their speed articulation and detail in the lower frequencies is the foundation for the rest of the frequency range. The ML3 power handling is huge! mainly because of the immense high power understressed Xover. 

      We believe the ML3 is the closest thing to the universal Holy Grail of balanced high end design that is possible to currently achieve. In a room of approximately 130 cubic mtrs or 4500sq ft the ML3 will play flat to near 25hz in the listening chair! And no it won't boom in the bass and be impossible to set up like many others. You won't for instance have to set them up 6ft into the room to get a decent balance. 

      In respect of imaging and soundstage depth the ML3's will throttle your senses. In our test room with the ML3’s set up 75cm (2.5ft) off the front wall and 2.75mtrs apart with a listening distance of 3.2mtrs image width is at least 2mtrs wider than the loudspeakers with 3 dimensional soundstage that goes back through the wall!! Belafonte live at Carnegie hall for instance is simply huge with tremendous image and dimensional stability. Detail within the soundstage we believe is currently SOTA (state of the art). Speed, bass slam and transient abilities are also currently at the leading edge of moving coil loudspeaker design. 

      The reasons for the ML3’s intrinsic superiority are many, but the unique and world's first acoustical foam baffle design probably heads the list. This baffle makes the enclosure of the ML3's ostensibly invisible to the low and high frequency drivers. Try this: put your hands around your mouth like your going to yell at someone 200mtrs down the road, but flatten them out so they don’t cup like a cone. OK, now turn to someone and recite a simple phrase, then take your hand away and recite the same phrase. The difference in the sound of your voice is of course amazing . You were listening to distortion of course and it’s obvious; Yes? That’s why all speakers with baffles of any sort are inferior. 

      ML3’s bass loading is proprietary, the port is huge and under stressed so that at high sound pressure levels it still supports the bass driver, in fact it’s close to linear at all drive inputs. Rock solid extended bass that does not produce a grungy type of incoherent bloom underneath the mid’s and high’s. The corollary here is phenomenal transparency that hitherto has only been the province of the best full range electrostatics but with punch weight and authority that the former has simply never been capable of. 

      As with all the ML series the Xover is hand built and hardwired. After run in each Xover is handtuned to each host loudspeaker in front of a measurement microphone to a virtually zero tolerance. Each Xover is subtly different to every other ML Xover because each Loudspeaker itself is an individual unto itself. The end result though is imaging and soundstaging perfection. 

      These Loudspeakers can pull off the ultimate disappearing act, no doubt.
