@ja_kub_sz Thank you for a well thought out comparison between the MMT, T200 and Musetec 005.
You have exactly the same priorities as myself, Solid State, dynamic wide presentation and I thought very interesting that you try to get a multi-channel sound from stereo, again excellent points. The only quality I would add is timbre or texture of instruments plus vocal realism - does Jagger really sound like Jagger including his London accent?
Your enthusiasm for DACs is reflected in my love of pre-amps. My very first HI-End gear was Naim, before they became famous. Naim always insisted that the pre-amp is the heart of the system but still adhered to the top to bottom approach of trash in - trash out. So most money should be allocated to the source, closely followed by the pre-amp.
Recently a new school of thought has insisted on the DAC creating the most influence. To this I say I believe it's a combination of the DAC and source that creates a true source.
Are you using the MM Streaming Card with your MMT? Or what's your source?
Regarding clipping it's usually a symptom that your power amp is too small, you're operating it at over 100% of its capacity.
You said the Musetec 005 doesn't cause clipping, these are its specs:
Single-ended RCA output level 2Vrms
Balanced XLR output level 4Vrms
@fastfreight advised to reduce the gain by 2V so I guess this would fall into line with the 005's 4V balanced output.
Good Luck!
