Amplifiers:A Keeper for Life. Do you know of one ?

My Neodio NR-600 Signature integrated amp. Tube sound without the tubes. Uses the Lavardin memory-distortion elimination technology. 100 wpc with remote control, and built like a tank. Preferable to any amp I've owned in the past 35 years (tube or solid state).

I have had experience with a ton of amps NAD,Marantz, Mcintosh,Einstein,Electrohome,Yamaha,Tecnichs,
Ayon,Leo Research,Bryston,Meitner,Coda TS,15,15.5 and the S100,
The S100 tops the list. It's pretty close to the best of the tubes and Iam not replacing tubes every 1600-2400 hrs

I know I'll regret stating this BUT...my newly purchased Pass Labs X150.5 tops my list of amplifiers - and it's a 30 year long list of Carver, Marantz, Conrad Johnson, McIntosh, Emotiva, Adcom, Rotel, Cayin...Audio Research.
Unfair to claim that this is my absolute favorite since the above list testifies contrarily to similar claims made in the past, but I will state that this won't be leaving my possession. If I tire of it for any reason or just get the "bug" again any time soon, this one will find good company along with my beloved Pioneer SX950 and my Marantz 2250b. Just can't let em go.

Audio research reference 250 for me and I have tried the following amps before

ARC reference 75
Parasound jc1
Ayre v1xe

@Oblgny if you like Pass check out Coda.
Two of Nelson's former employees at Threshold formed Coda
about 30 years ago.
Pass makes great product I just think Lauchli and Dale operate on a higher level of practicality which spells better value for the consumer.
