Hi, Henry14. Check out the excellent review in Ultra High Fidelity magazine no.62 just out. You can read part of the review for free at www.uhfmag.com. I find their reviews very fair and useful. They do their own thing and will respond to e-mail with good advice. Also, I've hear sim preamps make bryston amps sing on Tannoy churchills.....hope this helps, cheers, Bluenose
