MSB vs dCS Bartok

Got the MSB Premier, clocked in over 120 hours.

Honestly, not that happy at all. It’s OK and not bright.

But It’s not as dynamic compared to the Naim NDS /252 preamp I had before. It’s soft with vocals, bass is not punchy enough.

I do have the basic set up, just the:
MSB Premier DAC and only 1x Discrete Power Supply.

Will / should it get much better with and extra Discrete Power Supply and the Ethernet Renderer Module ?  Or do I need a quality preamp to make it sing ?
Or perhaps MSB is just not for me.  
Thoughts ?

Somethings not right, this is what a HiFi-News review by Ken Kessler had to say about the Premier’s dynamics.

Ken Kessler
"The Byrds’ 12-string jingle-jangle, is disarmingly well-recorded, and the MSB Premier extracted everything it could from the lush harmonies.

While The Hollies and The Beach Boys vie for the title of ’best harmonizing in a rock group context, The Searchers were no slouches either. This cover of the sublime PF Sloan composition treats the listener to dynamic swings and passages of sublime delicacy countered by the anger of the message. The Premier moves with the music so skillfully, so suavely that I was driven to A/B it with the LP.

The Premier? So lusciously liquid and resonant I was hard-pressed to accept the total absence of glassiness."

This is from the lab test.  https://www.hifinews.com/content/msb-premierpowerbase-modular-dac-lab-report

" Tested via its balanced XLRs in variable ’Low Output’ mode, and with the volume set to ’100’, the Premier delivers a maximum 1.675V from a moderate 36ohm source impedance."

1.7v is very low, did you try the "High Output Mode" which is some 3.6v output?

@rfc I have a similar -- identical -- experience right now with the Select. Midrange is fine, and there seems to be a bloom in the lower mids. It would seem that I am missing high frequencies and the bass is not punchy, it doesn't go very low -- basically, I'm missing resolution. Adding the reclocker (Ideon Master Time) made an important improvement as did changing to a single-core power cord (tightened the sound). 
I am probably doing something wrong and /or I am not used to R2R sound?

Hi George, yes it’s set up with the “high output”. I suspect that I really do need the Renderer Module. Using an Analysis Plus digital coax cable , not sure it’s the best was to deal with the digital signal.
