In a perfectly tuned system with the best hardware, modifying a single parameter can change SQ from unlistenable to musical bliss. matthias 1 Pareto Audio aka nuckleheadaudio Link to post Share on other sites
FredM Posted December 7, 2020 Author Share Posted December 7, 2020 2 hours ago, TheAttorney said: I've only just realised the significance of this. My DAVE AES input's limit is 96kHz. And I've just checked that my M-Scaler doesn't even have an AES input! Which severely restricts the options I have with MU1's AES output. The proof of the pudding will be in the hearing, but these limitations (not particularly MU1's fault) mean that I may not get the full potential of the MU1 with my Chord equipment, so may need a Plan B sooner than I had expected ☹️. In this fragment you can find an explanation what the FPGA does, and why AES-out is chosen. I don’t know how AES-96 will pair with the DAVE DAC. Indeed, the proof of the pudding is in the hearing 😀 56 minutes ago, lmitche said: Greater, for sure. Somehow I was quoted without typing the message 😁😁😁 lmitche 1 Link to post Share on other sites

FredM Posted December 7, 2020 Author Share Posted December 7, 2020 Indeed, synergy is key. From specs only it’s hard to predict, it’ll depend. The proof of the pudding is.. Link to post Share on other sites

It’s a true pleasure, the experience as I shared earlier still applies. Which reminds me, as you also use LS1be’s: Recently the Grimm LS1be were tested in a live session, together with two other active speakers (connected with a dCS front end). Great to see the reaction of the listening panel when the LS1’s played, even with goosebumps for the panel. Very familiar 😀 Here you can rewatch the session (the MU1 is also mentioned shortly) TL;DW https://www.grimmaudio.com/reviews/alpha-audio-the-ls1be-is-in-its-own-league/ Link to post Share on other sites
johnli Posted December 8, 2020 Share Posted December 8, 2020 I'm glad you're enjoying yours too FYI, the LS1 be will have an upgrade in both the DAC board and the subwoofer. it will cost money! Link to post Share on other sites

Perhaps techniques from the new MU2 DAC are reused in the LS1be. Interesting for sure, nice to have this upgrade option ahead, curious how it will sound 😀 4 hours ago, Darryl R said: Can anyone elaborate on the power supply in the MU1?

I had hoped for a little more info, but I didn't expect it. I'm very interested in any breakthrus in SMPS's for the server piece, as I'm so tired of messing with expensive LPS's. In my case, USB is the best option, and the MSB Pro-ISL/USB interface is integrated with the MSB Femto33 clock. Hence my interest in the power supply aspect. Link to post Share on other sites

I wouldn't know either, but they did significant updates for their software recently. One of them was that you can choose to play it with an output of 88.2, 96, 176 or 192Khz.

FredM Posted 14 hours ago Author Share Posted 14 hours ago A recent review on Stereophile, including some nice format conversion comparisons with the FPGA board (heart of the MU1). Ps. At home I even use the FPGA board for the FL and FR (active) speakers in a HT-setting 👍 (via Toslink to uncouple the HT gear with the stereo gear) CD Quote The same recording, upsampled to 176.4kHz and sent to the MBL DAC via the MU1's AES/EBU connection, was dramatically better. The tonal balance was still warm, but the congestion was reduced, adding depth to the soundstage and increasing the separation between instruments and groups of instruments within that stage. Lossy Quote Even lossy-compressed audio, like the 128kbps stream of BBC Radio 3's Night Tracks program, to which I have become addicted, benefited from the MU1's upsampling. 24/192 Quote I selected "The Trader" from the Beach Boys' 1973 Holland album, which I had ripped to a 24/192 PCM ALAC file. Now that was intriguing. [...] the sound was noticeably more palpable, with a better sense of rhythm, than the network connection. DSD Quote I had the same experience with DSD-encoded files, like Christian Tetzlaff and Lars Vogt's superbly idiomatic recording of the Brahms Violin Sonatas (DSD128, Ondine/HDtracks ODE1284-2D). There was simply more there there with the AES/EBU outputs. Summary Quote [...] And, especially via its upsampled AES/EBU outputs, it sounds superb. For those who can afford it, the Grimm MU1 is a highly recommended digital audio solution.
