On the website ASR, the now older RME 2nd generation DAC AKM4493EQ, has been measured as almost a top DAC and hence today are superseeded by newer.
However I claimed that the measurement has never been done with in my opinion outstanding “direct dsd” mode, which I claimed sounded superior. I should not have done that. Sitting duck hunting from the “grand contributors” specialists claiming if you cannot prove the claim with measurements, the listening experience is of no value and just yada yada… Every difference in sound is hence measurable. That is as firm as a physical law. Period. OK.
Now, have anyone done this measurement in a reasonably similar set-up as mine? I “feel” the difference is substantial to feed the RME, set to bypass its prorietary DSP, with a HQplayer resample setting as follows;
DSD256 DoP (max DSD speed), poly-sinc-gauss-xla, 32bit, 12880000 max bit rate, and auto selected actual bit rate by HQP, ASDM7v2EC.
Rest of setup:
- Source, Qobuz
- Playback and resample, HQPlayerd 4th generation (late) on Ubuntu Desktop (jammy) LTS
- NAA, self built PC running NAA image (latest), silent cool at about 16 dB
- USB output from NAA, Matrix Element H USB controller with isolated separate linear supply (Keces) and a comprehensive seal of any galvanical and airborn noise
- DAC, RME ADI-2 DAC fs, 2nd generation with AKM4493QE dac chip, set to direct DSD.
- Hypex nCore 400 monoblocks, custom filtering and anti-resonance added on speaker output
- Marten Parker Trio speakers
- Substantial attention to ground potential equalization between any of the hardware components in the rig and any signal path; network, analogue and digital, all shielded cabling, no radio transmission
- An almost ridiculous attention to mains, keeping it at a stable very low noise (15-16 mV @ 0-10MHz), no DC and no over-voltage transients.
Music from any genre has never in my life been presented with this kind of life-like accuray here at my place. IMHO I have the possibility and pleasure of compairing to other various systems.
I have recently been to Hamburg and Elbphilharmonie and enjoyed some classical music, one of the best musical experiences I have ever had, thanks to the new concert hall’s formidable acoustics. It showed how impossible sound reproduction really is, but nevertheless here we are.
I still claim the music reproduction from this RME is the closest to reality I have heard and that is compared to some pretty heavy condenders, conceptual and price-wise. It seems the particular game changing issue is the direct DSD mode? That unlocks a D to A conversion of its own? The usual claim of ■■■■ production is not not a show stopper anymore. Any of the old and gold tracks, eg Peter Gabriel - Sledgehammar and Cris Rea - The Road to Hell pt2, is no longer ripping my ears off and the level of detail and smoothness along with the partically inaudibe noise floor, makes any music and production quality quite enjoyable even if an inferior production is still a no-brainer to detect, but no longer a pain to enjoy. Is that measurable? Could that be presented in similar charts as ASR display?
