Anyone own Linear Tube Audio Amps?

I own the preamp and love it.  I've heard the amps at shows - they tend to run clean/lean if you are looking for a warm tube signature.  Possibly their ZOTL 40 with the EL34s would be the ticket - supposedly runs more of a tubey nature. Also their more powerful amp - the Fritz might be a little taxing for the amps.  They usually pair with high sensitivity speakers. Nicholas Tolson at LTA answers the email/phone there - he's pretty helpful and will steer you straight.

i have the current f/r lta zotl40 ref power amp, running various el34’s, i also have several arc power amps (ref110, ref75, and so on) but not an i-50

i would venture to say that my guess is that the i-50 will give a somewhat more overtly tubey sound signature than the zotl - which, because it does not have standard output transformers between the power tubes and the speaker load, has almost a solid state like degree of clarity, speed and frequency extension (but with better imaging, and more delicacy around voices) - also its el34 power tubes would have a touch more finesse than the 6550/kt88’s in the arc unit

neither will have anything near the bass grip of the pass xa25

hope that helps

I have the Ultralinear integrated and it’s fantastic. Great bass articulation and depth, amazing 3D soundstage, clear and extended treble…the works. Can’t think of how it could improve. 

If you are interested in detail at any cost then don’t consider the ARC i50. But if you want beautiful music rendered in natural tone with great detail then get the ARC i50! I have heard the other ARC integrated, they are beautiful… midrange bloom, fully fleshed out and detailed bass. I have a friend who has heard the i50… it is like the higher powered integrated. You will not need more power. The rhythm and pace (musicality) of the ARC is amazing, without loosing the detail.
 

You can see my prejudice by looking at profile for my systems.
