Hi Everyone. This morning I paired the amp with a Groove phono preamp. A really exceptional combination. No line stage or anything else. Super quiet, no hum at any level even full gain. Some tube hiss at really high gain levels that comes from the Groove. Not surprising as the gain in it is quite high and all tubes do have some hiss. Even the nearly -90db S/N has some. The amp itself has none. Since LPs have at best a S/N of about 65-70db the hiss is not audible. Probably 20db below the source (LP) noise of even the best records. Really clean sound. Exceptional response. Makes my neck hairs prickle. I used it with my shop turntable. A modified Pro-ject with a Jelco 370H arm, speedbox, and acrylic platter. Cartridge is a Goldring 1042. I used my AT ATF-MSH-7 phones. They are quite linear and smooth sounding. Some Sennheisers (HD280 Pro) I have have a slight tilt toward the low end and sounded really nice as well, just more bottom end. Not excessive and they might be something other folks would find preferable. If you need a phone amp this is the one you should consider. I figure it is one of my best designs. A real over achiever.
Good Listening
Bruce
