  1. 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
  2. Zamp is now sold. Thanks for looking.
  3. 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. Some links to reviews: http://www.6moons.com/audioreviews/modwright6/kwa100_5.html http://hometheaterreview.com/modwright-instruments-inc-kwa-100se-power-amplifier-reviewed/ Technical Specs Power Ratings: KWA100SE: 120W 8 ohms; 210W 4 ohms. Power Transformer: 500VA. Bandwidth: 10Hz – 100Khz (+0, -1dB). Noise Floor: -97dB. Gain: 26dB. Input Impedance: Min. 15K 50Khz; 23K 1Khz.

  4. 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.

  5. 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).
  6. 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.
  7. 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.
  8. 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

    Least Significant Bits of the 24 bit music files.
  10. Bridge 2 MQA

    MQA terminology. I guess its because an MQA file is playable without any decoding at 44.1/24 or 48/24 rates (though it won't be equivalent to a standard PCM file at those rates).. The info from the higher rates is folded back into the LSB's and extracted in the 'decode' process. Hence unfolding I suppose.
  11. Bridge 2 MQA

    Bill, if you let me know the titles that weren't unfolding correctly I can try them with my DSJ. That might help uncover if there is some issue with the Bridge. Cheers Paul.
  12. Bridge 2 MQA

    It does IMO. I have a family Spotify subscription but I hardly ever listen to it myself because I find Tidal SQ much more compelling. OTOH MQA titles are so limited that it doesn't hold great musical interest for me, regardless of SQ (so, at least for now, I wouldn't be pushing MQA as a reason to get Tidal).
  13. Bridge 2 MQA

    Bill, what are the problems you are having with the PS Audio? I used my Android phone as a remote and didn't experience any playback issues with my DSJ - which reported MQA and the correct unfolded rate during my testing. The question mark for me is still whether the better sound from some Tidal MQA recordings is not just the result of a different master/filter. There's even some scuttlebutt on the internet suggesting a specific up sampling filter can make MQA files sound better than an actual MQA 'decoder'. In any case I can't see MQA being the game changer that is being reported by some of the audio press. New formats have only ever gained a foothold when there is marked step-up in perceivable quality or convenience to the 'average joe'. Don't think this is the case with MQA and I doubt the opinions of the minority audiophile market will sway the case. Without widespread support it will die commercially. Frankly I won't be sorry to see it go - I'd prefer to see the real hi-res masters become more widely available for purchase and streaming. Qobuz seems to be leading the way with this - hope that service becomes available in Australia soon.
  14. Bridge 2 MQA

    I have a PS Audio DSJ and have done the Huron and Bridge 2 firmware upgrades. I've had a listen to MQA using Tidal via the Bridge 2 - but have found it a bit of a non event. The DSJ is a great piece of gear but frankly I get better sound via the usb input than via the Bridge 2 option. What's more I haven't found MQA to be consistently 'better' - and even in the cases where it is, it's impossible to say whether this is because of different mastering or the insertion of the (software based) minimum phase filter which is used as part of the MQA 'decode' process. One would have to use a similar filter on the 'standard' file being compared to get even close to an apples to apples comparison. Color me extremely skeptical of the whole lossy MQA process. I'd take the unadulterated master any day - and let me season to 'taste' using the dac/filter of my choice.
