  1. Bit of a long shot, but has anyone compared the MOS16 and MOS24 on SQ, especially with 24/96? I’ve owned the MOS16 for a year, but have mostly used it up till now with the UPL16. At the moment I’m using my MOS16 with a Bryston BDP1, output via UTOS and it sounds absolutely excellent, especially with 24/96 via Qobuz or from file, even though the MOS16 only processes as 16 bit. Very detailed but unfatiguing and way better than might be expected for a £300 DAC. I’m thinking of buying a MOS24 as well and wondered whether SQ would be an appreciable strip from MOS16? As well as “native” 24/96 ability, I understand that the 24 bit version uses higher precision resistors, for example.
  2. Other than unpacking compressed data does the “first unfold” apply any proprietary DSP as well? In other words is there a reason why you might anticipate that it would sound different from a straight 24/96 file? I also note that some MQA files stay as “24/48” after the initial decode, what’s going on (or not going on) there? Thanks.
  3. I’m midway through my trial month with Qobuz Studio. I have a Bryston BDP1, which I understood that Bryston had limited to 16/44 when playing Qobuz directly (as opposed to via Roon) However, my 24/96 Qobuz favourites play fine and show as 96:24 in the Bryston Media Player pane (with appropriate bitrate) and as 96 on my DAC readout. Obviously I’m not complaining, but good to hear from other users who can confirm the same and/or explain. (Already enquired on Audiocircle but without reply so far). Thanks.
  4. The thing is, enjoying MQA isn’t just about swallowing the marketing speak, many MQA-labelled releases sound good and when coupled with the initial novelty of on-demand streaming, it’s quite a compelling proposition - you suddenly have lots of new and great sounding music at your fingertips. Even some of MQA’s harshest critics (including CC) have admitted from time to time that it can sound good. However, true hires streaming services like Qobuz have made MQA redundant, so choosing a DAC because of MQA compatability seems a pointless cul de sac now. I was certainly disappointed with the “full MQA” experience via my Oppo205, compared to letting Roon do the initial decode, while the (ostensible) same releases in 24/96 or 192 FLAC via Qobuz sound better still.
  5. Thanks, that’s a great suggestion (other than price). Despite being a Mirus owner I’d forgotten about the Herus. So this should work with the current Apple lightning to usb converter without any additional power supply?
  6. Thanks. I should stress that my iPad has a 3.5 jack and sounds quite good with the onboard DAC. I’m looking for something that improves on this and plays 24/192 and DSD without downsampling etc. From one of the links you posted, this surprised me: ”Cozoy implemented a Cirrus Logic CS42L42 chipset in TAKT with the ability to decode audio formats of up to 384 kHz/32-bit resolution PCM, as well as native DSD decoding of up to DSD128, however, due to the use of Apple’s LAM (Lightning Adaptor Module) based on MFi design requirement ensured that TAKT can only deliver 48kHz/24-bit resolution due to the LAM upstream limitation.” Does this mean that digital output via an iPad’s lightning port is restricted to 24/48? If so, it renders my query redundant. This device seems to be exactly what I was looking for, but has been around for a while now and hasn’t generated a lot of attention: http://www.hifiheadphones.co.uk/shanling-up-portable-lossless-headphone-amplifier-usb-dac.html
  7. As seafood or our galactic overlords? In view of the possibility of the latter, I refrain from the former. IMHO not a good look to have to admit to the octopoid invaders that you’ve been chowing down on their relations.
  8. A pithy summary of the entire “Starship Troopers” franchise.
  9. Looking for something ideally like the AQ dragonfly (in terms of form factor and not needing its own power) but capable with at least 24/192 and DSD 64. Does this exist, or do I have to go up to a Chord Mojo or equivalent to play these formats on the go? I presume all also require use of the lightning Usb3 adapter, rather than direct connect to lightning (6th general iPad)? Thanks.
  10. I’m not sure I see any evidence for that claim; if anything I see greater agreement for the proposition that the particular chip or DA conversion methodology used is way down the list of the major influences on DAC SQ. For an alternate viewpoint, at Audio Science Review a lot of the best received DACs are ESS or AKM based. By contrast, Amir has published very poor test results for some non delta-sigma DACs.
  11. So your understanding is that we will be able to run current UPL > toslink to ElectroTos adaptor>ElectroTos> new fractal DAC?
  12. you’re obviously not familiar with the UPL - sequentially numbered files in sequentially numbered folders, WAV only, no tags (unless you like surprises...). Navigated by folder number and file number, toslink only, only one DAC input, battery powered. The one slight saving grace is that it’s about the best replay of RBCD I’ve ever heard...and at c.€800 for both DAC and transport.
  13. Thanks. As I read this the developments are: a new DAC (I’m not clear what the “fractal” is all about, presumably this will still be some form of ladder DAC?) with an optical interface that will only work with ElectroTos, not regular Toslink. the ElectroTos being an optical converter with the implication being that this will be offered in different versions to suit the source interface at one end (?) and will be user configurable as normal Toslink or EC designs’ optical at the other end a new UPL with onboard ElectroTos. Is this your take on it? I hope the new stuff will still be available at “pocket money” prices. I put the UPL/MOS combo back in my system yesterday and it sounded absolutely brilliant, very special in the mid range and upper bass. And a bargain too, normally you have to spend a lot more for this level of inconvenience in hifi. Having said that, the MOS16 alone fed by UTOS from my Bryston BDP with Roon/Qobuz sounded a lot better than any £300 DAC has a right to.
  14. Thanks. I find this stuff fascinating. The three channel approach seems to predate what Mercury were doing by two decades- don’t know if there is any link between Robert & Wilma Fine and Bell Labs? I note there was an AES event to celebrate 50 years of stereo in the 1990s. Helmut Krueger may have even attended. It would be good to hear from any CA members who were there.
