OP--It's kinda all over the map on the Freya. I know Kdude thinks it's junk. I saw ghosthouse rave about the JFET in another thread.
Here's a third take. Some of this is culled from what I wrote this morning on another thread. I mostly got it to try a passive and stay balanced. Tubes and JFET were nice tweaker bonuses. I very much like it for the value. I use it mostly as a passive with a Cary DAC200ts. It works well for me like that and so fulfilled its primary purpose. To add some tube flavor with a push of a button is great and certainly helps with some bad recordings and such. Between the options on the Cary and on the Schiit, it can be a distraction, because, if there are buttons and knobs, I like to push them and turn them.
That said, unlike ghosthouse, I haven't made friends with the JFET stage, but that almost certainly relates to different gear and preferences. I don't think the tube stage sounds as good as many other tube pres (anything I'm comparing that to, though, is also more expensive). With the stock tubes, it was pretty sterile and didn't add a whole lot. To be fair, I probably didn't give them sufficient time to burn in. I've tried maybe half a dozen or so combinations--didn't like it with Sylvanias (VT-231, GT, or GTB) or Raytheons. Very much prefer it with GEs, RCAs, and/or KenRad. I didn't try 6sn7w or TS BGRP...I refuse to put tubes in that cost nearly as much as the Freya (or more), especially when the tubes keep burning in the other modes. I don't find it to be as responsive to tube changes as some others, though. I don't find it to be noisy--one pair of known-to-be-noisy tubes was actually much quieter in the Freya than in a Cary pre.
One note--the remote doesn't do on/off, and the switch is on the back of the Freya, if that matters. If you don't need the balanced and aren't interested in the passive or JFET push-button tweakability, still easy enough to try and I think good for the money, but probably could do better on a tubed pre for not a ton more dough, but more dough nonetheless.
So, on that, if primarily looking for an unbalanced tube pre, I generally agree with Kdude that there are other places to look for that. Although I haven't heard the LTA, sure seems like an awesome piece. What folks are saying about using it as an amp on high-efficiency speakers just blows my mind.
