The ideal starting amp for under $2000 is the Rogue Audio Cronus. Yes, it is an integrated amp, but it has active preamp stage, not passive like most of the rest. If Ihad $1900 to spend on an amp alone, I would get Quicksilver Audio's Mid Monoblocks, but then i would need a preamp, so I would get a Mapletree Audio SA-2 linestage preamp. Next up would be a Manley Stingray integrated for $2400 and then after that I'd look at the Manley Mahi Monoblocks possibly with their Shrimp Preamp. OF these, only Quicksilver is a small outfit, but it has been in business for 20+ years. All hand wired, point to point. 2-3 week turn around. Never misses a commitment,or so I am told. Otherwise I would stay away from small boutiques the first time around.
