Anyone own Linear Tube Audio Amps?

A couple of other things. I have Spatial Audio Labs X5 speakers so the bass isn't an issue for me since the woofers are driven by hypex class D amps. The other thing I forgot to mention which I think is a big difference (beyond the warmth that the EL34s have over the KT77s) between the EL34s and the KT77s is that the KT77s put the vocals up front. It's almost like having a really clear center speaker in a HT set up that puts the dialogue out there front and center. It was a bit jarring at first but it has actually grown on me.

Quick update, I added Psvane EL34s to the mix and I'm really loving it. Hearing things I didn't know were there in the music. 

Older thread, but based on my recent experience I’d love to add my two cents. I purchased the Linear Tube Audio preamp and have had it in my system for about a week. 

Wow… I’ve just been utterly impressed with the unit. The marriage of the solid state details with a tube tone is the perfect description. For me, it’s endgame equipment. Sitting here listening to old recordings feeling like the artists are in my living room. Enthralling. 

I had the complete opposite experience. I bought a 6 month old LTA40 + integrated with NOS Mullards thinking this was my end game amp and that it would blow my Raven Blackhawk away. Owned it 2 weeks, didn’t like it at all and resold it for no loss. Nice to try but the problems were it lack that deep full warm resonate bass, sounded to SS/neutral lacking that tube full analog/warmth. I listen at lower volume (50-70 db) which was not this amp’s strength. When I turned the volume up is was better. Installing Gold Lion KT77’s improved the bass and clarity.  It just sounded veiled/muffled at lower volume.  I even compared it to my Home Theatre amp on another system and had the same result.  Don’t get me wrong this amp sounded incredible at higher volume. Realism, soundstage, quiet background, separation of instruments just amazing not in a tube amp way.  What I did learn was like that traditional tube sound and full detail at lower volume. Not the outcome I was expecting at all!

Some folks like old tube amp sound because of the transformer distortion. You will not find such distortion in ZOTL amps. I can say that I have a very early version of the ZOTL40 and have had it upgraded with the latest “plus” mods. Early on there was an issue matching to some speakers but the new mods have made it come alive and are so crazy good that I will put the LTA ZOTL40 up against anything out there.
