New reference amp for my system--the Unison Research Sinfonia!
We have a new amp in the house--the Unison Research Sinfonia! This is going to be my personal amplifier for a while, and after just a few hours with it I'm very, very happy.
It's a single-ended parallel design that uses Tung-Sol 6550s (KT88s can also be used) to get 27 beautiful watts per channel. In comparison to the newer S6 amplifier, this is a more "classic" tube design that offers a smoother, warmer and more seductive sound. The S6, which has been my favorite Unison amp so far, sounds a little "faster" and more linear, but the Sinfonia has this romantic, addictive sound that's better suited to classical music. I'm currently listening to the TrondheimSoliste LP I reviewed just a few days ago, and the forward presentation I found "bracing" now sounds more balanced and musical.
And since it's Italian, it has to be gorgeous! I love the stainless steel plate on top, and the wooden chassis that's finished in cherry (with a matching cherry remote).
I have a big pile of CDs and LPs to review, and now I can catch up. In addition, the FedEx man is currently driving around Central Texas with my Giro turntable, which was just returned by Dave Clark of Positive Feedback Online--review will appear shortly. Once I get my Unison Research Simply Phono phono preamp back from reviewer Michael Mercer, my reference system will be once again intact--for the first time in 2012!
