Many thanks. Before we switched to the Vitus SM-103s, we tried a variety of other amps, including MSB, Gyrphon, Westminster Labs REIs, Pass Labs, and a few others. Once the 103s broke in the decision was immediately clear. You can’t unhear them, so nothing else would do.
I think MSB makes some great amps, but for me both their DACs and amps lack the warmth of natural sound. Not everyone is the same, so I can understand why some would like them. Our EMM DAC just barely edged out the Select II in our earlier testing. This said, I could have lived with the Select II, but it wasn’t my favorite. I didn’t know that they weren’t even recognized in the 2022 products of the year - I guess I need to read my copy. They did just come out with their Director. So, this may change the sound for the better.
I have listened to over 1000 Expensive Solidstate amplifiers and non of them come close to Vitus amplifiers. Vitus spend over 8 years to design an output stage for power amplifiers.
I have compared SIA-025 to Kondo 300b (Speaker was Wilson Alexandria X1 Series 1 around 95db over 4ohms) and Vitus was wonderful .
I do not say All DD speakers are good match with Vitus but if your speaker have good matching with Vitus and Vitus have enough power to drive the speaker then no SS design will sound better than Vitus.
Vitus will introduce 1.500.000 euro Studio Design Series (Transport/DAC/Pre/Power) in the future.
