Tube Mono-Block Recommendation

Atmasphere I did consider OTL but reading online about OTL amps being unreliable, tube eaters, get extremely hot and expensive to maintain is sort of pushing me out and trying to consider something else. Want something more plug and play.

+1 for CAT JL2

Dragon vibe, what you've read has nothing to do with Atma-Sphere OTLs. These are perhaps the most bullet-proof and utterly reliable tube amps made. And, they are one of the few tube amps (only?) that match ALL of the characteristics you listed in your opening post. The only issue is whether your speakers are reasonably compatible.

I will research into it. Big Amps they look like Monster trucks. Over 20 tubes Each block :-) I wander how long those tubes will last. everything I have read about Atma has always been positive.

I hate making a decisions specially so when I cant hear all the gear in my own setup.

Speakers are Whisper XD so might need Ralphs expertise to check them out for me to see if they will match well.

Quicksilver V4 Mono Blocks. Great sounding, reliable,no nonsense amplifiers with plenty of tube choices to choose from.You can also save some money for other goodies.
