Does a Tube Dac make sense?

The only answer to that question is get the MP AND the RME side by side in your system with your ears for some time. Return the one least liked, whatever the reason(s).
Report your experience, which is more valid than blather.
If $1K is a significant amount to you, do it right.
Not by fishing in the impounded pond of forum opinions.

I had a CAL dac with a tube output stage 15-20 years ago when digital was harsh. Modern dac's/recordings/streaming services are so much better I don't look for tone controls anymore.

you participate on this forum for a while, you realize there are some usernames who are here just to issue blanket dismissals... i suspect they are now pretty much deaf but can still see and can type

There certainly s a wide range of confidence with which opinions are tendered! ;)

@stibin,
I’ve heard a number of tube DACs and they can range from just okay to superb, same exact experience with transistor DACs. The sound quality will be determined by the talent of the builder, design, part quality, attention to detail and implementation.

Musical Paradise has earned a good word of mouth reputation. I would seek clarification in regard to the return policy. If you find it satisfactory I’d get it and judge it based on its sound quality in your system. This the only way to really sort it out. The general dismissal of a DAC with with tube output stage seems illogical and without merit. Execution of the product is the key.
