  1. Focal Utopia vs Sennheiser HD800S

    Yeah, I was exactly the same - I didn't want to tear the leather or break the ear pad. I just used the serial off the cardboard box!
  2. Focal Utopia vs Sennheiser HD800S

    Perhaps - though I believe some (early serial) Utopias with driver failure have been replaced by Focal under warranty. My point was that you stated a 1yr warranty for the Utopia and this does not appear to be the case. Hope you're able to get your headphones fixed without too much drama.
  3. Focal Utopia vs Sennheiser HD800S

    FWIW, I bought my Utopias locally from A2A and registered them with Focal. My returned certificate states a 2 year warranty.
  4. Roon

    No, I haven't tried that. The thing is I want to have the ability to use the TV screen with Roon - looking at album covers etc isn't quite the same on a little tablet or phone. Sometimes I also like to do some desktop computing while listening to music....actually I'm doing that right now! I expect disconnecting HDMI wouldn't be nearly as influential as disconnecting USB because the former is not connected to the DAC - but it would seem everything has an influence with computer audio. I previously preferred the USB connection to the network bridge on the DSJ. The Mac/iFi USB decrapifier are both powered by an Uptone JS2 linear supply and the gigabit ethernet switch is powered off one of the super regulated iFi ports (5V). Not sure if it's software changes or other tinkering that has swung the pendulum in favour of the Network bridge connection for me. Maybe I just changed my preference.
  5. Roon

    I've been critical of Roon's SQ - preferring Roon/HQP or Audirvana. However I've recently gone back to evaluate Roon's stand alone SQ using the network bridge connection to my PSAudio directstream Jnr. I'm using the Precise Minimum phase/power of 2 up sampling filter - sounds pretty impressive. I get best results with the usb connection from my Mac Mini to the dac disconnected (i.e. only the LAN cable to network bridge connected). I use my TV screen or a small monitor connected to the mini to navigate Roon - couldn't stand using something as small as a phone for my main listening setup.
  6. FS: Modwright KWA100 SE power amp

    No it was built by a couple of other SNA members - @Full Range and @Green Wagon http://www.diyaudio.com/forums/pass-labs/278695-upgrade-f5-f6.html
  7. Zamp is now sold. Thanks for looking.
  8. Item: Modwright KWA100 SE Power amp Location: Bendigo Price: $2500 including shipping Aus wide Item Condition: Excellent Reason for selling: Not required Payment Method: Pickup - Cash, Paypal, Direct deposit Extra Info: I recently bought this amp from @Whites here at SNA to evaluate against my Pass F6 - specifically to see whether I would benefit from more power (the Modwright is 120W/8ohms and F6 is 25W/8ohms). Turns out that the F6 is sufficient for my listening, so I'm relisting the Modwright for the same price I payed with shipping included. The KWA100 SE is a Class A/B amp, beautifully built with premium parts. Current Australian retail for this model is $8200. The SE model has the beefed up power supply/output stage, Modwright caps and Takman resistors etc. You can read more about this upgraded model at the Modwright web link: http://modwright.com/products/kwa-100se-amplifier.php Would suit someone looking for valve like tonal qualities combined with SS muscle. Ships with manual in original double boxing.

  9. tem: Parasound Zamp V3 power amp Location: Central Vic Price: $400 including shipping Item Condition: As new Reason for selling: Surplus to needs Payment Method: Pickup - Cash, Paypal Extra Info: This is a terrific little amp with Parasound's big amp DNA running through it's circuits - and even some design input from the Master, John Curl. At 45W/8ohms or 90W/8ohms bridged, it can drive most reasonably efficient speakers without issues.. Supposedly Parasound's CEO, Richard Schram, even uses them to drive Quad ESL-63's in his office! Has some great features: trigger(with multiple settings), signal passthru, adjustable gain and even a front headphone socket. Due to it's small footprint it would make a fantastic power amp for desktop monitors - any pc card, headphone amp or dac with volume controlled line outs could be used as a preamp. Retail in Australia is around $700, so this is a nice saving on a practically new amp. Comes with original double boxing, manual and power cord.

  10. I think Roon sounds quite good, but I've found it to lag behind the SQ of Audirvana in direct comparison. When HQP is added it becomes more interesting. HQP has a bewildering array of filter and noise shaping options which subtly change the sound. I've tried most of them but keep coming back to the 'poly-sinc' filter with standard 'TPDF' dither. Especially with well recorded acoustic and vocal music (though it sounds fine with everything) this gives the most natural, focused and layered sound with best sense of space and ambience. The only drawback with using HQP is that it introduces a slight delay to initial playback start and hence a bit clumsy compared to Roon by itself (or A+ for that matter).
  11. Roon just used to drive me crazy with all the button presses required for simple playback. With the one touch playback I find it sooo much easier to use. My only question is why this took so long to add? SQ too is excellent when used with HQPlayer. I was thinking of giving Roon the flick (my year subscription is almost up), but now thinking I may need to re-subscribe.
  12. Bridge 2 MQA

    FWIW, I tried about a dozen more MQA files from the Mconnect app to the DSJ varying between 44.1 and 192 - they were all played back at the MQA rate reported by Mconnect. The PS Audio seems to be working correctly to me.
  13. Bridge 2 MQA

    Bill, I had a play with the MQA albums you mentioned above. I can confirm that the DSJ does indeed play back 4:44 and Lemonade at 24/44.1, Bandwagonesque plays at 96/24 and 11:11 plays at 88.2/24. These rates are precisely what the mConnect app specifies the MQA files at - so nothing seems amiss. Weirdly, Audirvana specifies the same MQA rates but then up samples 4:44 and Lemonade to 88.2/24 - which I believe is incorrect, they are just 24/44.1 MQA files i.e. not encoded at the higher rates. Cheers, Paul
