I have the Onix SP3 integrated amp. I bought it strictly on Srajan Ebaen's Six Moons review. Previous to that, I was seriously considering a Conrad Johnson CAV-50 EL-34 based integrated amplifier. I am so glad that I bought the Onix SP3. The CAV-50 has that lush EL-34 sound that can be alluring, but some of the music that I listen to just didn't have the dynamic punch it should going through the CAV-50. The Onix SP3 has the PRAT (pace, rhythm and timing) thing hands down plus the liquidity of tubes. It will never have the tone of an EL-34 amp like the CAV-50, but that tone and warmth are more colorations in my opinion. If that's what you're after, then go for the EL-34 amp. The Onix SP3 has the immediacy and ability to convey musical emotion found in some SET amplifiers.
