Samuel T Cogley Posted April 2, 2018 Share Posted April 2, 2018 1 hour ago, AMR/iFi audio said: Here's a little more insight about our approach. We do not do things by halves. We write our own software code so our customers receive two specialised XMOS firmware versions: v5.30 – optimised for MQA v5.20 – optimised for music file formats up to DSD512/PCM768 (non-MQA) Each firmware version squeezes that last ounce of sonic performance to suit each customer's preferences. Just as car enthusiasts load different ‘remaps’ into the ECU (Electronic Control Unit) for their preferred driving experience, we let our customers load their preferred ‘file format remap’ for their own music torque curve. Hopefully this is all clear now. Also, micro iDSD BL isn't the same as its nano version. It goes further than formats supported. The bigger one does things its smaller sibling won't, their functionality isn't the same. Hello iFI Can you explain the technical reasons that the MQA firmware (5.3) disabled DoP256 on my iDAC2? I re-flashed 5.2A, and got DoP256 back. And just a suggestion for your download page(s): You should explicitly tell people that the MQA firmware disables DoP256. I can't find any mention of it there. Thanks EDIT: PS: You might want to re-think the "file format remap" concept. Many people (that I know, anyway) don't have any DSD256 files but use HQPlayer to upsample Redbook files to DSD256 and beyond. I count myself in this group. Link to comment
luchoh Posted April 2, 2018 Share Posted April 2, 2018 @AMR/iFi audio I think if you call this tune/remap rather than "firmware upgrade", people would be less bothered. I personally have iDAC2 and iDSD BL and I don't plan flashing the BL, while I flashed the iDAC2 immediately. Still comparing the results of MQA/iDAC2 vs HQPlayer@DSD512/iDSD. All via RCA outputs, to minimize the headamp differences. Finally, I am grateful for your efforts and as a software engineer understand why you had to make sacrifices to retroactively implement something to a system it wasn't designed for in the first place. Sorry it somewhat backfired on you. Link to comment

The only rational explanation I can think of is that a firmware including both DSD512 and MQA support wouldn't fit in the XMOS flash memory. If that is the case, why not just say so? Link to comment

I know the bigger one does more stuff, but only on the amplification/battery/headphone/filter department, not on the DAC department, which I clearly stated. Even though I/we appreciate what you've done and that on top of that we all have a choice to go back and forward with these 2 different flavored firmwares, I still can't understand why a DAC which is more powerful can't do more than one that is less powerful.

When you say "HQPlayer@DSD512/iDSD", what are you feeding HQPlayer to upsample? MQA, 16/44 PCM, or a mixture? Hey MQA, if it is not all $voodoo$, show us the math! Link to comment

I need to clarify that the MQA -> iDAC2 is served not via Tidal, but Audirvana. I haven't tested if there is a difference between Tidal and Audirvana yet... so many things to do - so little time.

gabeg Posted April 3, 2018 Share Posted April 3, 2018 I have an idsd Bl and did the upgrade but I don't get a magenta light, I get a yellow one. Thoughts? Link to comment
zubek Posted April 3, 2018 Share Posted April 3, 2018 From release notes: Quote For the micro iDSD BL & micro iDSD: MQA LED is Yellow I have a different situation: I've updated the firmware and setup MQA passthrough in Tidal, the music is playing but I have the regular (red book) green LED not yellow. I have verified the firmware version (5.30). Used macOS 10.12.6 (Sierra) to update the firmware. What software are you using to feed your unit? Link to comment

The iFi DACs (other than iDSD Pro) provide only MQA renderer support, so you need TIDAL to decode MQA. MQA passthrough in TIDAL should only be used if you have a DAC like iDSD Pro that does both decode/render.

macuniverse Posted April 3, 2018 Share Posted April 3, 2018 @iFi Audio, many thanks for making this alternative update available on the older gen devices. Most appreciated. First time I was able to sample some Tidal MQA tracks in their native format and, through iDSD silver, they sound really good. PS. I agree with some other posters that the loss of functionality after the (alternative) update needs to be made clear on the download page. Link to comment

You could show your support for the consumer by doing this. Keeping concurrent version numbers would also help, for example having a 5.3 and a 5.3DRM 5.3mqa instead of privileging MQA development...
