May I share my little dilemma?
For context: I now play with a Holo Spring 3 Level 2 DAC with preamp module built in -- with Afterdark Rosanna streamer and a DI-20HE both fed by a good Afterdark external clock. I upsample evrything to DSD256 (offline or on-the-fly) and am very happy. Also, an Audio-gd HE-1 Vacuum is on its way to compare with the Holo preamp. Before this I had Lampizator L/B7, Terminator 2 and Musician Pegasus (strangely enough in that order). With the Lampi and Holo I clearly prefer the SQ with DSD, and that includes PCM-upsampled DSD. With the Terminator and Pegasus the difference between PCM and DSD was less pronounced.
I read about the theories people have about PCM and DSD, and why one should be better than the other but, honestly, I do not take these very seriously. It often seems that these theories are used to reduce cognitive dissonance of already-made-up minds. My ears often tell me things that are at odds with these theories -- either way, depending on the specific setup. I am not for one or against the other format, it all depends on the gear involved. I continue to like to be surprised.
In spite of my proclaimed happiness -- you know the audiophile itch -- I am again investigating a next DAC and two are left to choose from: Merging (Hapi or Nadac, allow me to count them as one), and Audio-gd R7HE. Very different beasts indeed. Pros and cons (for my use case), partly factual, partly imagined:
R7HE pros:
- synergy with my beloved DI-20HE
- external 10MHz clock input (allowing me to use the Afterdark clock)
- tweakable (NOS, upsampling, PLL etc.)
- ACSS (although currently of no use)
RH7E cons:
- I trust the R7HE house style and all the raving reviews, however I do not know how it performs with DSD
- bulky and heavy
Merging pros:
- Ravenna protocol, simplifying my setup (alas this includes saying goodbye to DI-20HE and EtherRegen, which will be of no further use)
- undefeatable DSD performance as claimed by many
- volume control (not a real pro as I probably will not use it)
- multichannel option in case I take the 8 rather than 2 version (neither of immediate use)
- word clock input
Merging cons:
- possible mediocre PCM performance (moot if I only play DSD)
- the word clock input -- if used -- requires an additional device, such as an Antelope OCX HD
- no I2S or USB input (although the RJ45 input takes care of the higher resolutions up to DSD256; that is the whole point)
Anyone heard both these DACs?
Do I have to worry about the R7HE's performance when playing DSD?
