Onix SP3 Integrated Tube Amplifier

Onix SP3 Integrated Tube Amplifier

If you think audiophiles are boring just yell out “tubes are dead” and watch the energy bow the windows. It’s one of the most passionate discussions outside of speaker wires in the stereo world. I first became a believer in tube sound in 1987 when I picked up a used Conrad Johnson PV-7 preamp. To this day I kick myself every time I think that I was ignorant enough to trade it in. During this past summer my yearning for a tubular reunion came to a head. Knowing that integrated tube amplifiers were the easiest solution and fit in well with this e-zine’s mantra of affordability, I went onto audiokarma.org and began checking into the various possibilities. After a few days of reading, I contacted the good people at AV123 and inquired as to reviewing the Onix SP3. Sean was more than happy to assist, and a week later a rather heavy 60pound package arrived.
