Primaluna?

I had a Primaluna Dialogue Premium Integrated for a number of years. Really satisfying in late night listening but as some mentioned it did have limitations on headroom. 
 

also I had a number of problems with Upscale Audio tubes. I got bad input tubes at least three times and they refused to do anything about it and just said our testing is sufficient. So not a great experience on customer service for tubes. 

I eventually auditioned an LTA integrated and was blown away at the comparison between the two in terms of how much of a veil came off the music with the LTA that the Primaluna had. Maybe the auto bias, maybe the design, maybe the tubes, who knows but it was undeniably better with the LTA. 

Better than Raven. :)

I have an Evo400i, I immediately replaced the stock tubes with NOS Philips EL34. I got a matched set of 2x4 for around $1200. After a few weeks one tube blew. I got worried so I took the bottom of the amp off and measured the voltages for each tube, all good. I also admired the wiring. I got another NOS EL34, replaced only the bad one, works amazingly. Then another tube blew, so I got again only one replacement. The good thing with auto bias is that you can do this plug and play, and it works perfectly. Imagine replacing a whole set of 8xNOS tubes every time on blows. These tubes have been manufactured in the 70’s, it’s quite usual to have some blow. And while waiting for the replacement NOS I plugged back the original PL tube, worked perfectly…

It’s been running on average 4 hours/day since almost 1 year, I can highly recommend it. Sound quality is awesome, but it depends a lot on your sources, speakers materials and cables. 
I’m looking to get a Decware at some point, and I think PL will have a very good resale value in case the Zen sounds indeed better:)

I was introduced to PL last year when a buddy brought over a Dialogue One for me to listen to. He runs the top of the line VAC pre/power amps but started with the Dialogue One. He has >500k into his primary system. He listened to my system and didn't think I was getting the most out of my Magico A3s. Magico Speakers have a reputation of not being the easiest speakers to drive. He was correct! The Dialogue One sounded AMAZING with the A3s but didn't have quite enough power. My wife came up to the listening room and said "How can you go back to the Yamaha after hearing the PL?" She's not into the stereo that much so for her to initiate the decision to upgrade amps was a great and welcoming sign. 

I went with the EVO400 power amp after auditioning ARC, Ayon and Dynaco amps. The EVO400 drives the A3s incredibly well! Amazing body, sound stage and overall sonics. My buddy came over after I got the PL and said he was impressed with how well the EVO400 drove the A3's as well with the overall sonics. His speakers are Magico S7s. 

You get great bones and choices with PL. Ultra Linear or Triode modes, Auto Bias, etc. Being able to run any power tubes in the amp gives you tremendous choices to tailor the sonics to your liking. 

This year I'm planning on adding the EVO400 preamp with a separate phono preamp, The Herron VTSP-3A is the front runner on my short list.

Keep in mind that there is so much that goes into having good sonics. I've heard people say that the room accounts for 50%. Prima Luna is a good bet to be highly satisfied with your amplifier choice considering all of the factors that go into generating awesome sonics.

Better than Raven. :)
