Summary:
Getting better and better in sound and reliability. A five star performer. Terrific looking since day one. After 16 months of use and tube swapping, I still enjoy these monoblocks to the extent that I lost interest in auditioning other great products. Integrated well with two REL powered subs (Storm III)

Strengths:
Loves low impedance speakers. Life time warranty to first owners Sounds like no typical SET amps

Weaknesses:
Need over 90 db, simple crossover speakers to work best

Similar Products Used:
$1,000 range solid states and push pulls (from ADCOM, Acurus, Carver, Jolida, SF TPC Assemblage). Also heard AudioNote amps at length.

Summary:
For more detailed and complete reviews, please refer to the stereo version SV84C and SV84CS (select version) else where in this site. They sound reportedly the same as these monoblocks, just having a bit less power.

I bought the most recent SV83M monoblocks from Steve's High Fidelity Engineering (a.k.a. Decware ZEN), and this is the 3rd weekend I have them. I feel they are still breaking in, and most other veteran users said they keep improving after months of listening.

Even driving the 86 dB Magnepan MMG, the SV83Ms show a musical purity that is very satifying. Like most SET the SV83Ms have liquid midrange and sweet highs. Unlike many other SET amps, the SV83Ms' bass is tight, articulate, and realistic; their highs are extended. Their overall music representation is always faithfully precise, wonderfully musical when the recording calls for. These amps are damn fast; the starts and stops of musical passages can be startling. Listening to the SV83Ms and MMG at night and low/modest level is a treat: The music is so good I don't feel missing too much bass. As always, I can add a subwoofer whenever I like, but I prefer sans-sub except for movies.

A follow-up with more details reviews will be submitted once I get the 93 dB HornShoppe from Ed, www.thehornshoppe.com. The speaker will need a couple weeks for break-in.

My associated components:
