@tkukielk I wouldn’t really view the PL and LTA as substitutes as they’re quite different. The PL will have more of the traditional tubey warm sound while the LTA will sound more neutral but still with that tube magic, so it really comes down to which type of sound you’re looking for and prefer with your equipment. As such I’m not surprised at all that @cbrez finds the LTA pre with his XA25 to be a synergistic combination. and LTA does offer a trial period that you might consider taking advantage of. Frankly, if you can afford a little more than the LTA I’d go for the Spatial Audio Raven that is probably a best of both worlds option between PL and LTA, and they also offer a trial period so that’s absolutely what I’d do. And I should note that the Raven is fully balanced where the LTA is not, which is a consideration given your Pass is a fully balanced amp. Just some thoughts FWIW, and best of luck.
Linear Tube Audio version 3 of the MicroZOTL pre
LTA has announced a version 3 of the MicroZOTL preamp. From their website, it sounds like a fairly significant upgrade. I reached out to them and they mentioned refinements in bass and the high end.
There is also an upgrade path for current MicroZOTL owners. Wanted to share for LTA owners and fans.
