You could be right. Maybe Hans has lost quite a bit of hearing in the higher frequency. I'm curious to hear it myself.

Listen to it, you'll hear what I'm talking about. It is not a bad product at all, I am just used to that attack and visceral aggressiveness Rob presents and that crazy depth and edge and instrument variation, live music is like that.

Mr Watts .... my dear sir --- my dear, dear sir ...
Please comment on the importance (or non-importance) of conducting square-wave tests, especially over >1k. Say, 12k.

Rob gave his opinion of square wave testing for dacs over here several days ago.

does anyone use RCA to XLR cable for Dave and a Balanced amp for the best of both worlds?
Also going over -3 db would affect sound quality? say 0db.

I wouldnt do that as your are probably binding your amp's inverted signal pin to ground and possibly earth. Unless your amp has a single ended mode option by means of a switch.

If your amp has a RCA SE input, use those with Dave.

all my searches point out that RCA to XLR is as safe as RCA to RCA, the only caveat is it will bring an unbalanced signal.
I plugged in and have been comparing RCA-XLR vs XLR-XLR and when I volume match, it sounds much better, especially in clarity and detail.

I was very much interested in Mu1 and now MU2. Looking forward to your comparison to Dave! However, now that Roon is sold I would be very cautious buying a product that solely relies on Roon. I hope that Grimm hasn’t shot themselves in the foot.

@Rob Watts check this out:


This guy was an engineer in Belden for over 30 years and his cables focus on getting time right, he has a ton of technical information and white papers, no snake oil with this guy.

Wait, Roon was sold to another company? Can you explain what you mean?

 

[GuiltyRocker]

Never mind I just saw it was acquired by Harman, oh no. These big companies destroy whatever they touch, this is bad news.

Another reason why i love having my music on file and backed up.. it cant be taken and wont change

 

[Meridian7]

Yeah, hate greyed out holes in a playlist.

Good thinking, I have two NAS drives here, with a ton of music on my personal cloud.

My DACs will always show a square wave as the ideal bandwidth limited square wave - that is with ringing and overshoot, without clipping, as it's important that the ringing and Gibbs phenomena is preserved. The lack of clipping is simply down to including an appropriate overhead in the digital filter to accommodate Gibbs.

You can see bandwidth limited square waves and read about Gibbs phenomena here.

If a DAC does not reproduce ringing with square waves then it is seriously faulty, as the interpolation filter is not bandwidth limiting. This will have severe SQ problems, as transient timing will have gross errors.

I've listened to a few of these DACs recently Rob, the transient accuracy is so bad it all sounds like overly-liquidy overly-soft syrupy disaster.

Which models specifically?
