1979- SAE MK30 (used with original Polk audio 7 speakers, proved unreliable).
1983- Yamaha B6 (shaped like a pyramid, seriuos power, able to attain concert level volumes with the Polk speakers- perfect for my college years).
1993- B&K ST1400 (a sweet sounding solid state amp)
1996- Conrad Johnson MV55 (a beautiful EL34 amp, sweet, midrange timbre eerily convincing. Excelled on jazz, classical, rock less so)
2003- Sugden A21a (the grand daddy of British Integrateds, very musical, as close to tubes as possible for SS amp, but also hottest running amp I have owned)
2001- Pass Labs Aleph 30 (famous Nelson pass class A solid state sound, proved to be a little under powered for my needs)
2005- Rega Mira Integrated (My first Rega amp after using a Rega turn table and cdp for years. A pretty good amp. Got due to pratical considerations- less energy consumption, no tube purchases, and simplicity plus freedom from heat and hassle of 3 above amps which for me were desirable in winter and undesirable most of the time. I sought an amp for all seasons)
2008- Rega Elicit second incarnation (My amp for all seasons. Got when first released in US. Has the bit of extra refinement and musicality one expects from a top class British integrated. Alot of my feeling about it is in agreemnet with an online review at six moons audio
http://www.6moons.com/audioreviews/rega/elicit.html. Loving it with the RS3 speakers and Jupiter 2000 cdp- the combination continues to captivate)
