Ultimate Integrated amps

IMO the Vitus 030 is the sweat spot if you want an ultra high end integrated with no compromise that can equal 50k worth of pre-power.Regarding the d'Agostino you pay a lot for the case work unfortunately.I would not put my money on the Aavik but that's my own opinion.

At about $23K, the T+A PA 3100 HV may be part of your list, albeit cheaper than $30K

Why are people so fascinated with ultra high end amps ? Most of the time they look pretentious and right out ugly, often of course speaker dependent, a LFD amp or Lavardin would sound just as well, if not better, amps with lots of watts and mammoth power supply is not always giving the best sound, often a nimble Alfa Romeo is better that a Lamborghini!!! Maybe if we were better choosing speaker with easier load, then the smaller amps would arguably be better sounding than an overbuilt mammoth!This was written with tongue in cheek ;-) in part...

Just because you are not going to pair a $15k integrated with $100K speakers.I don't see a Lavardin integrated driving a pair of Wilson Alexx, just makes sense.Regarding T+A, it might me a very good amp but this brand just like Aavik doesn't hold it's value IMO as opposed to Dartzeel, Vitus, CH Precision, d'Agostino, Gryphon, Luxman, Accuphase, Nagra and others to name a fiew.I would be careful when investing such a chunk of money in an amp of whatever gear that is.That doesn't mean T+A and Aavik are not good, they just lack image IMO.

Yup.  Any integrated over 80 lbs hits the sweat spot.
