Equipment Reviews
As a result of the ever-increasing demand for a full-function preamplifier with a level of performance substantially above that of the SP17, we are pleased to introduce the striking new SP20 vacuum-tube preamplifier. Influenced by some of our classic groundbreaking SP preamplifiers but with performance that is only achievable by our best LS- and PH-series designs, the SP20 offers inspirational performance combined with real value. The look is reminiscent of classic Audio Research components, but is totally modern with a clean, purposeful esthetic. The front panel sports a new 4. Those large knobs rotate fully, are optically-coupled and speed sensitive; turn it slowly and the volume will change incrementally; a quick turn one way or the other will raise or lower the volume by a large amount. Also for the first time, the Input selector is on the left, the Volume control is on the right. Through the touchscreen one can change Inputs, select Stereo or Mono, Mute, adjust Phase, adjust left-right Balance, and adjust the phono input Load 50, , , or 47k Ohms.

The frosting on the cake is that all of this quality and value are packed into a case whose beauty rivals almost anything on the market. I guess he liked it. I'm very close to buying a Ref5se but I love the idea of the SP20 with the phono stage.

Suffice it to say, gone are the days of a half-dozen toggle switches, mechanical push-buttons or old-school rotaries. The optically-coupled rotaries provide level and source, everything else is adjusted via the touchscreen. And a beautifully-made metal remote covers all bar the most rarely used subsidiary functions. Comprehensive in more ways than even the feature-laden touchscreen menus imply, the SP20 is perfect for , as it also addresses the current twin revivals of headphones and the LP. The onboard phono stage is quiet enough, musical enough and fine-tuneable enough to preclude any hunger for an outboard unit, while at the back are the RIAA phono input plus earthing post, four single-ended line-level inputs, two balanced XLR inputs, separate monitor-in and record-out for recordists, and two pairs of balanced outputs. A tube-hybrid, the SP20 contains four valves within — a pair of 6H30s for phono stage duties and another for the line stage.
It was controversial at the time and some say it almost destroyed the company. Opinions about the sound quality are all over the map but based on dealer comments and my listening, it wasn't exactly world class. Age has also taken its toll by now and I found my unit nearly unlistenable with LPs after a brief evaluation. Conventional steady state measurements showed nothing seriously wrong with it, but the music had no life.
I read a lot on this topic today.
