Congrats on considering AVA equipment. Most folks don't have the privilege.
I encourage you to spend some time on the AVA website, especially with the archives of the "Audio Basics" newsletters. When you read over them, it's hard to escape that Frank Van Alstine has incredible experience (30+ years), background and insight in understanding audio equipment.
When you buy something here, the money goes for superb design, careful construction, and high-quality parts, not for marketing, a "status" brand name or a chassis that resembles a boat anchor.
There are thousands of opinions about amplifier design and audio equipment in general. Even before I bought any AVA equipment, I was very impressed by Frank's continuing passion to get sound reproduction right. That's his business. It's about music. It's not about twinkling lights, tiny buttons and shiny titanium.
After using the FET-Valve amp and the T7 preamp for months, it's easily the best value, and likely the best I've ever heard in a showroom or in my home. Extended, natural frequency range, lots of detail, tremendous dynamics, zero noise. It sounds as close to live as anything I've heard.
Go for it. You'll be glad you did. And there's a satisfaction guarantee, if it doesn't work out for you.
Good luck.
