Q-Acoustics Concept 500 Speakers and Moon 240i Amp

Recommended Posts

Hi Gibbo,

Thank you for the post. It's very interesting, especially what you say about the Moon 240i! 

 

When you say the Moon 240i sounds similar to your new tube amp (but with less tube flavor), do you mean that only the Moon 240i vs your DAC+preamp+VTA M-125? If so, it's impressive!

 

Can you tell us what preamp and DAC are you using with the VTA M-125? Is it a SS preamp? Is it a Delta-Sigma DAC?

 

On the other hand, I've got tempted by the devil again!! :-)   I bought the Line Magnetic LM-508IA (valve integrated amplifier) as I read rave opinions on different forums about it and the LM amps and I bought it directly from a chinese official dealer at less than half the price published in Europe and USA (with upgraded WE replica valves included). I will receive it in two or three of weeks and I will let you know my impressions. People say its a music monster... we'll see! I'm very ansious!  :-)

 

Regards,

Hi Pedro

That Line Magnetic looks like quite a beast - 48 Watts of pure Class A if I read correctly.  Looking forward to hearing about it when it turns up.

I have been pick and mixing between different components.  Stand alone DAC / Pre-Amp is Marantz HD-DAC1 which (as far as I understand) uses the Cirrus CS4398 chipset which I believe is Delta Sigma, and analogue volume through motorised Alps pot.  Moon 240i DAC stage is Sabre ES9010K2.

All perform well with the Q-Acoustics and I find quite close in sound quality (clarity, sound stage etc.).  Moon DAC and power stage is the leanest at the bottom end, but that mainly seems to be the DAC stage.  The Marantz through either the Moon power stage or M-125's has better bottom end, with a small edge to the M-125's with the KT120's.

I keep eyeing off the Benchmark DAC3, but that may need to wait a while.

The Q-Acoustics continue to be an easy load to drive and happy with any competent front end.

Hi Gibbo

Thanks for the reply. I've got the picture.

 

Yes, the Line Magnetic LM-508IA is 48W pure class A single ended. It's not just the power, but the reviews talk about a incredibly dinamics and soundstage. I think it has the power and sweetness together. We'll see. I can´t wait to hear it!

 

On the other hand, have you tried any Ladder DAC? Like Schiit or Audio-GD. I have the Audio-GD R2R-2 and it's very very nice. It has an analog sound (if you can call it that way), dinamics, a "LOT" of detail, etc. It sounds beautifully. Before this DAC I had the SMSL M8 wich has 9018 Sabre chip and, even considering the price difference and that I liked the M8 (its a very nice budget DAC), the sound of it was much more digital (again if you can call it that way) and thin (less full bodied). I would suggest you to try one Ladder DAC, if you can borrow one.

 

Finally. The LM-508 has a preamp input and I'm thinking on buying (latter on) a preamp. I'm leaning towards the Audio-GD C2 preamp that matches perfectly with my DAC and it's a completely bargain, like all of the Audio-GD stuff. I'll think about it.

 

Of course I think we can say all of this because the C500 are incredibly transparent and show everything your gear is doing! These are the keepers!

 

We'll stay in touch. Regards,

Hello Mungbean66,

Sorry for the delay.

 

Well, as a "restless" audiophile, I've done many tweaks on my system since the last post, and they all worked, some more than others, but all helped improving the sound.

 

Today I'm buying DH Labs Power Plus AC Power Cord (it has very good reviews) and some Wattgate conectors to make three DIY power cables at a very modest price because I think the power cords are the weakest link in my system (I still have the original power cords and a AC multiple socket that you can see on the pictures attached). Nevertheless, today my system sounds like heaven, really AMAZING. 

 

Let me say what I have today:

 

Notebook (regular) with i3 processor with Windows 10 streaming with Tidal app.

Dirac Audio Processor with filters digitally correcting Room Acoustics.

Audioquest Jitterbug as passive USB filter

Wyred4Sound Recovery USB reclocker to help the DAC with the jitter

DH Labs Silver USB cable

Audio-GD R2R-2 DAC

Kimber Timbre RCA interconnects

Line Magnetic LM-508 integrated valve amp (impressive with original valves, but incredible with upgraded ones)

Tungsol NOS 6SN7 matched pair (my favorite among many I've tried)

Tungsol NOS 6SL7 single (the same opinion, I LOVE this brand, I also tried a pair of 12AX7 on another amp)

Genalex Gold Lion 300B cryo (very nice)

Psvane 805A TT Collection (much better than the original Psvane 805)

Kimber 8PR speaker cables biwired

Q Acoustics Concept 500 (with out words to describe them)

Bada LB-5600 power filter

PS Audio Noise Harvesters (3 units)

All conections (power cords, RCA, speaker cables and valves pins) have Mapleshade Silclear applied on, a very nice improvement in sound I would say.

 

So, I have been busy!! 🙂  Next stop, DH Labs Power Plus Cord for the amp, the Bada Power filter and the DAC, and I FORGOT TO MENTION.... I also have on the way a HiFi Tuning Supreme fuse for the amp!!! 🙂 

 

Of course, I also took care of speaker positioning. I have not to many space to move them, but I've tried my best on what I have.

 

Today I cannot believe the sound, it's incredible!!! Really really really outstanding. The perfection is from another world and I'm sure will improve (I hope significantly) with the power cords and the fuse.

 

The thing you get with SO MANY tweaks on a great system is a transparency that it's not just every single detail on the music, but unbelievable perfection in tones, instrument air and separation, complete black background, deep and wide soundstage, tons of dymanics and PRaT (the LM-508 is a monster on this field) and zero harshness. It's incredible!!

 

I send you a couple of photos. I hope I answer your request!

Thanks for the update mate, definitely answered my question. I still miss that SET sound. Your a lucky man with that system.

 

Unfortunately I needed to go a different direction (speakers and amplification) for my system. Fortunately, I made some great choices and I'm loving the sound I get now.

Hey Pedro,

 

Apologies about the belated reply mate.

 

I started off with a pair of Hifiman HE300 headphones and after a year of headfi, got a cheap system my wife bought me. 

 

It was a Yamaha R-S300, a cheap turntable and a pair of Jensen X1 speakers (quickly replaced by the Q Acoustic 3010). I eventually got a very good deal on a pair of second hand Monitor Audio S6 speakers and started using them. The amp changed and the 3010s and the R-S300 became a secondary system. The sources were a Pioneer PLX-500 turntable (with a Rega Exact cartrdige) a MHDT Labs Paradesia 3 DAC. Cables have remained generic or DIY jobs.

 

Slowly I upgraded everything and I now have a Schiit Saga Pre-amp into a Aspen NASKA 80 power amp into a pair of Hulgich Serenade loudspeakers and lastly a Lengend Acoustics Kurlette Sub. The sources are a Lenehan PDX (feed by a ALLO USBridge streamer) and I am waiting for a HifimeDIY UDA38 DAC (9038pro based DAC) to arrive for my PS4.

 

If I am honest, for a long time I wasn't really happy with my system and I spent a lot of time and a small amount of money selling and buying. I found that a lot of 'high end' stuff I had heard (through other people) although amazing was ruthless and unforgiving of source material. After listening to a mates impressive but more modest system; I realised I wanted to enjoy all music and not only the music that was recorded well. His system was fantastic and what most audiphiles would consider 'musical'.

 

So the PDX Dac, in combination with pre and power amp were a big step up in sound quality. Not nearly as big as the speakers though, they were a revelation. Everything became much clearer and better defined; including bass. The music is more enjoyable and some songs even give me chills. Ultimately, I no longer feel the need to change anything which I think is a good indicator that I've built a system that suits me.

 

Apolgies about the long winded reply mate.

      Extra Info: 
      Up for sale is my Simaudio Moon Mind 180 HD network streamer with the Swagman Labs 12v Linear Power supply.  
      The MoonMind 180HD has the latest firmware and can stream local files as well as Tidal, Deezer and Internet Radio.  The unit is well reviewed online and Simaudio is a high end manufacturer, this is a quality audio streamer/renderer. I have had both the microRendu streamer and the MoonMind in my set up for a few years and both are very good, but the MoonMind just shades the microRendu for SQ.
       
      Input is via Ethernet or WiFi, but Ethernet of course gives the best operation. The 180MiND outputs signal via the following digital connections (Toslink, SPDIF on RCA, AES/EBU on XLR)

      Item: (Now sold) Simaudio Moon P5 Preamp (with remote) 
      Location: NE Victoria
      Price: $1800
      Item Condition: Good
      Reason for selling: Funds for repairs  
      Payment Method: Pickup - Cash, Paypal, EFT
      Extra Info: Free delivery to Melbourne next week.
       
      I have owned this preamp for the past 11 years (purchased S/H from A1 Audio) and it has run faultlessly. 
       
      A couple of years back I purchased a used Aesthetix Janus as I wanted to see how a valve preamp went in my system. I enjoyed the Janus and also it's flexibility of having all inputs both SE and balanced. Unfortunately, it became faulty (previously meddled with) and was sent back to the US for repair and upgrade which cost a bomb! So as much as I would like to keep the P5 as a backup (and second system preamp) I have to move it on to help pay for the upgrade of the Janus.  
       
      Strongly prefer not to ship the amp, as I don't have the original packing.
       
      I have noticed the a small amount to the txt from the front of the premap is missing and there a a few fine marks on the top panel. The scratches on the top of the power supply as from the spikes on the premap. Also the LED on the power supply doesn't work (which seems to be a common problem with the P-5)
