Of all your gear, what piece impresses you most?

My turntable cartridge. Such a small device to make a huge difference in sound.

@ AIT, Man!, I have to agree with Grannyring, what an awsome pair of amps!, what brand and model speakers is that you have in the pics, you still have them, they are eye candy as well, how do they sound, what are the specs on those babys?

The headphones...Sennheiser HD800.

A basic rule in audio - change only one component at a time.

Fortunately I had experience with each system component prior to buying the Janszen zA2.1 speakers. So there is no doubt in my mind they have impressed me most.

So soon I hope to experiment with other upgrades, including a new room later this year.

Audiolabyrinth,

Those are Infinity RSIIb speakers, circa 1985. I've completely redone them with an external passive crossover featuring NorthCreek and Solen Heptalitz inductors and Mundorf and Duelund caps, new midrange diaphragms from Apogee Acoustics, rewired them with Cardas copper litz in teflon. They are excellent sounding, and not an easy load for an amp, but the above SET handles them beautifully.
