Amp upgrades under $3K for bookshelf system


Hello all,

I am looking for suggestions given the mind blowing number of options available. I currently own a Onkyo TX-RN626 Home Theater amp that I am looking to upgrade. Its been fine for general TV surround sound but I am now only looking to power Sonus Faber Venere 2.0 Bookshelves with a Energy (also could be upgraded/removed) powered sub. I have a Technics 1200MK2 Turn Table for Jazz Vinyl primarily. I really want something that can give me great sound at relatively low levels in about 1000 sq ft of general listening space. Living room/open kitchen with wood floors. I am looking to stay under $3k but have some room if necessary (used suggestions are great). I don't have a phono preamp but would certainly factor that in as part of the system. Thanks in advance.

Take a look at the Kinki Studio EX-M1. I recently got one and it's exceptional at low level listening, has wonderful soundstaging that's just as detailed and robust at the sides as the center, and has over 215 W per side. It's the most resolving amp I've heard that I can afford.

All the best,

Would a big McIntosh (for example) that's in good shape but a few years old give me that? So many great deals on used gear at a 50% or more discount to be had but I don't know how to begin deciding. I don't have a local audio store in my area that I could sample so looking to you internet gurus :-) for help.
