When were the best tube amps made?

@larryi agreed.

I can accept KT88,but not KT120,KT150, or more.

I still think my Lamm ML2 (original model) are wonderful but you need very efficient speakers.

@clearthinker - I had an SP-10mkii for many years, what a glorious piece-- it was the last of the old school ARC tube preamps. It definitely had issues with microphony--but that phono stage was glorious for its time. I finally did sell it and went with a separate line and phono stage set up  (which has evolved over time) but that preamp was a classic. That is what you were speaking to, yes? 

Two Days Before the Day After Tomorrow….

The best are made right now.

There seems to be a consensus here: Today is the era of best tube amplification. And: some of he best stuff comes from artisan electronic designers. I just took delivery of a Supratek Grange phono-/pre-amp. I have not yet hooked it up because I am building a new vibration-attenuated instrument rack, and the concrete inside the tubes takes forever to cure. But the enthusiastic testimonials from Supratek users over the years had me pay attention. Communicating with the designer, Mick Maloney from New South Wales was free education of another level. This is an important point: today’s designers have so much more information at their hands compared to previous generations, that one can find new approaches to solving very basic problems such as SET linearity, source impedance matching, forsaking SUTs, etc. almost every year. I am currently a user of the "legendary" Sunvalley EQ1616D phono-pre, sporting a magnificent ELROG 274B rectifier tube: this was my first foray into tube territory, and I never looked back since. It will be for sale pretty soon, I guess ...
