Theta Prometheus Monoblock vs Bryston 7BSST2

I concur with Bill, Bel Canto has a superb track record with class D amps. Their older REF1000 Mk.2 was an absolute sonic jewel at an attractive price.

REF600 is not based on NCore NC1200 like Veritas and Prometheus, but on a yet unnamed NCore trickle-down module.... Sorry, I am still trying to find out some details....

REF600 utilizes an apparently standard Hypex NC1200/700 SMPS in each chassis. One thing unique about REF600 is that John Stronczer -- the designer -- has implemented a custom differentially balanced input stage to lower noise floor, raise common mode rejection ratio, and raise input impedance to 200KOhms.... I have not heard this amp yet, but outwardly it does look intriguing.

Thanks for your fantastic response. I had read your review about a month ago and I was looking for someone to do a comparison of the Veritas with the Theta. I cannot do this since I do not have my complete system yet (amp and speakers missing). How about you taking on the challenge? Your writing is excellent. Seems Veritas is keen for someone to do this,

"I would be happy to provide a pair of the Merrill Audio VERITAS Monoblocks for the comparison. I have also offered Stereophile the Merrill Audio VERITAS Monoblocks for review.

Perhaps there could be an independent, neutral place where the A/B comparison is done side by side. I understand some have done the side by side comparison and hope they will share their findings."

The above quote was posted on the Stereophile web site on the Theta review.

It would be great if Theta is interested in this comparison.

Hi YYZSantabarbara, a comparison of Veritas and Prometheus would make interesting reading....

But it is more likely that you will continue to find reviews that are targeting one product at a time.... You might need to continue drawing your own comparisons by unscientifically reading between the lines... Particularly tricky if the two articles are written by two different reviewers.

I have a dealer who loaned me these amps for a week to
use in my own system. It was rather cool to read the
Stereophile review after already having listened to these
amps. They replaced a Mark Levinson 335. By coincidence
the reviewer's amp is the ML 334. Similar voicing as the
No.335 but less power. I must say that I am in love with
the low end, the dynamics, the wide open soundstaging,
and layers of detail within that same soundstage that are
now present. The sometimes slightly dark sounding
midrange that the 3 series has on some systems is gone. I
ended up buying the amplifiers! The amps I had in
my system to listen to for several days prior to the
Prometheus were the D'Agostino Momentum monoblocks. No
way I could afford five of those! I had a good comparison
to make my decision.
