Small balanced monoblocks

You should add the Bryston 7B-ST monoblocks to your short list. They are of reasonable size, offer a combination of excellent power and sound quality (rated "Class A" by Stereophile mag), and have a 20-year transferrable warranty backed by probably the best service in the high-end industry. A new pair sells for $5000, and can often be bought used for around $3000-3500.

With your BAT preamp, consider BAT VK60's mono. Used for around 5k. Not exactly small...but great match with the wadia, 3i and speakers...

Have you considered the BAT VK-500? It's a single unit with two monoblocks in the enclosure. Two power cords, two power switches...

I would add Clayton M100 monoblocks to your audition list. Output is rated at 100 watts / ch. class-A. It has both RCA and XLR inputs, and its relatively small size would fit your living room as well. Check out www.claytonaudio.com for more info.

Happy Listening!

I second the opinion on the Classe CAM-350s, my present amps. But if your speakers don't need that much power, before the Classes I had Pass Aleph 2s, and they were wonderful. There is usually a pair or two used on Audiogon.
