Linear Tube Audio version 3 of the MicroZOTL pre

@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.

Cbrez my unit is out for #3 upgrade this  . I will fill everyone know  the magnitude 

the upgrade it’s pretty comprehensive  on mainly now on a much larger # costly double sided Ceramic circuit board loaded with A much larger capacitors ,power supplies, and even better soft tubes will last even longer by design.

Knowing build quality well the prima luna is not in the same league

Look at the output you dont use a low quality attenuator 

Round silver can either Alps or Bourne  attenuator very  inexpensive 

And robs low level detail.
