Should I get the Art Audio Jota

OK, maybe I'm thinking wrong. I've been considering the 17LS a strength in my system and my intention was to maximize it's virtues with an amplifier upgrade. I wasn't aware that there were preamp designs specific to single ended amps.

A phase that is being inverted by a component doesn't require correction elsewhere because up to 50% of all recording have been recorded with inverted absolute phase (unintentionally).

Some recordings have inverted phase but it usually sounds, to me at least, as if only one or two mics were the culprits. The sound becomes "phasey" and puts pressure on my ears. Some of Hendrix's stuff was intentionally recorded out of phase, but I have jazz and pop recordings that are obviously just mistakenly so. On a good system (like most of us have) the phasey-ness becomes obvious.

I've heard recordings where the piano and sax sound great but the drums and upright bass are out of phase - they pressurize the room in uncomfortable ways and seem to be smeared all over the soundstage.

By the way, the CJ 17 and 11 are both a bit "fuzzy" sounding, kind of like looking outside through a window screen. The AA would be more like the window without the screen.

If your room is small to medium sized, the high current AA should work great, depending on the kind of music and at what levels you listen.

Hi Tomryan,
That was pretty much my thinking, and while I've only listened to these two seriously as a set, I'm presuming that the 11a is by far the fuzzier of the two. I'm also hoping that with the right tube upgrade, I'll be able to find a synergy between the 17LS and the AA. My plan is to buy an amp on the used market so I probably won't have the opportunity for audition. I definitely wouldn't want the cj to exert such an influence over the AA that I would never hear it's special attributes; in fact, I was hoing for the opposite.

Phaelon - "I wasn't aware that there were preamp designs specific to single ended amps. "

Hi, I didn't mean to imply there were actual topologies specific to preamps used with SET amps. Just that there are sonic unique sonic traits in the best SET amps - their own form of transparency, tonality, etc. that is not readily apparent or existent in push-pull amps. So, if a designer/manufacturer is only fine tuning their preamps via PP amps, they would never notice these traits missing or degraded.

I'm not saying SET is inherently better than PP, each has it's benefits, just that is distinctly different in it's sonic presentation. Preamp designers who also build SET amps or work with them make sure these traits are preserved.
