You will get plenty of folks to tell you that you scored large, and I agree. I found a BEL 1001 Mk V 3 years ago and ran it in my system, changing out with my other amps (I kept most the others, putting them in other systems.) I was very happy with the tube like warmth, but in a very honest, no frills package. Imaging was stellar, and the soundstage deep. I found a 2nd Mk V a year later, switch the toggle on both to mono (on back panel), and bi amped my Meadowlark Blue Heron II's. Magic! This setup retired a Musical Fidelity Trivista 300, ARC VT 130SE, McCormack DNA-1 (Gold + mods), and a Pass X250.5. I have tried a Gill Audio Alana pre (modded), Aesthetix Calypso, but settled on a Hovland HP 100 (tweeked by Mr. Hovland). The BEL's mate well with tube pre's.
You may have found out, but Mr. Richard Brown was an electrical engineer with an intense interest in audio. He worked for some audio component companies (I'm not sure which ones), but started making his own amps at home. Those who heard them wanted ones for themselves, so he went into business, sort of. He had a lousy but completely honest business plan: he made everything himself, he tested each unit until he was happy with it, he never compromised or cut corners, and he sold a damn fine amp for relative peanuts. Unfortunately, he died after a very brief illness in the fall of 2010. I don't think anyone picked up the mantle; mainly because this is a currency driven business and Mr. Brown did it for what appears to be the love and pride of his workmanship. Keep your amp; they will become rarer and at full retail price, are still a bargain.
