Grimm MU1 Streamer - Really "The Best"?

@lalitk +1

The day before yesterday I connected an Atlas Mavros (copper) AES between my N20 and DAC. Just interested to see if I'd been missing something regarding AES.

Well started listening yesterday evening and it was sorely lacking compared to the USB. Granted the USB is solid silver, but they are both similarly priced.

With AES music was less separated, sounded congealed with less micro detail and above all zero PRAT.

I could easily tell in a blind listening test. The USB being light, airy with high tops and clear bass. Timbre and textures were excellent too. Vocals were real.

So I know my Musetec 005 is USB optomised but as @lalitk said even all your downstream components can influence the sound.

Anyway we'll find out for certain when you get your cables.

@latik In stating I was sold on Antipodes, I was within days of purchasing K50 when I was notified the custom build streamer I ended up purchasing came up for sale. Again, K50 was my choice based on the second ethernet port optimized for output to second streamer, as you know still my preference at this point. I had nothing against the Aurenders or Innuos, simply fact Antipodes had the nice AES AND network outputs.

@lordmelton , interesting results of your AES testing, thanks. Not suggesting this is the correct way to think of it, but Audioquest’s AES Diamond cable costs 2.5X their Diamond USB cable (both silver). Just raising the question of whether an equally priced AES and USB cable should be expected to perform equally or not. Audioquest’s pricing suggests not, but I really don’t know.

Later I switched to a Network Attached DAC with external clock and power supply. The N20 connected to my DAC via LAN (no USB or AES cabling) and re-clocked by external 10MHz clock was a different beast all together. The effect of external clock on N20 was pretty startling to say the least. The channel separation, lower distortion and a greater phase clarity became the hallmark of music signal. The new level of realism, more analogous, intimate presentation with external clock in the mix especially with higher resolutions files.

Forgive me if I’m missing something but if your dac is “network attached” then the N20 will have virtually nothing to do with the performance of the dac/clock.

Your aes vs usb test is very likely a null result…if you were to get your hands on a really good aes cable and a similar quality usb cable you might hear an accurate outcome. Very few (unless your dac has an inferior aes input and a supercharged usb input) would arrive at your conclusion. The N20/Aurender aes implementation is quite often the preferred output. The clock in the N20 is quite good…

@sns , I edited your statement for accuracy:

"I’d be very interested in your comparison of AES if when you did get the Antipodes"

Trying to stay committed to giving each of these three and the Statement too (which Nuno at Innuos has actually directly offered to send to my local dealer, who is not an Innuos dealer, for me to try).

I’ve been deliberating whether to continue with the "buy used" route where possible (the MU1 may not be possible), or to try to switch to working direct with dealers/companies to get a demo. From a cost perspective, it’s not all that different really, after I compared all the possible outcomes. Maybe it’s just me, but I’m always apprehensive of involving dealers/vendors unless I’m fairly confident I’ll buy a particular product, and involving 3-4 vendors in this with all the shipping involved seems excessive to ask of them all, when I will in the end only buy one of them. I did conduct a Shunyata vs Audioquest shootout for power cables where they each sent me demos, and I ensured both companies knew what I was up to at the outset. Shunyata in particular was extraordinarily helpful through the process with proactive communication from Richard, and for the most part I chose Audioquest only because of personal preference.

As I said, Innuos generously offered to send a demo Statement for me. With Antipodes I’ve heard they offer 30 day returns when buying direct, which would work for me. And Grimm is more restrictive - they offer a 14 day return policy as part of their purchase contract, but only from the time they ship the unit, and they require tracking info when returning the unit for proof it was returned on time. I guess it’s doable but that would be rushed.

If I proceed with buying the used K50 for sale now, it means I may need to involve my dealer with the Innuos and Grimm servers (I think we get around the import duty if it’s sent to my dealer, or at least I never directly pay for it), and I’d feel bad if I chose the K50, or the N20 for that matter, in the end.

Trying to figure out the most reasonable path to trialing all 4 servers without putting out the companies and dealer too much. I’m totally willing to pay for shipping and their time helping set this up, but I don’t think that really helps from their perspectives.
