Just an update with my Onix SP3/Reference Mk II/XCD-88 system--I have since filled my speaker stands with sand, swapped in some Groove Tubes 12AX-7M (Mullar reissues) preamp tubes, swapped in a new Zu Cable Birth power cord on the SP3, and swapped in a Zu Cable Bok power cord on the XCD-88. The components have close to 150 hours on them while the Zu power cords have about 80 hours. This system is incredible with an expansive sound stage, precise imaging and better tonal balance from lows to highs. When I first installed the power cords, I thought I wasted my money. The sound actually lost a bit of energy and was a bit thin. I decided to keep playing on with the premise that Zu Cable claims their power cords improve with burn-in. I can say that their claim is true, and I am so glad I jumped on the Zu Cables on eBay.
I think a lot of people have been prematurely dumping their Onix SP3 amps and Reference 1 monitors. These components have really given me the opportunity to experience high end audio on a budget. I have auditioned some nice gear like the Chord Electronics monoblocks mated to Tetris loudspeakers (the same speakers used by Herbie Hancock and engineer Steve Hoffman). The Chord and Tetris system worth close to $60,000 is state of the art. When I went back home from this, I thought I'd be very disappointed in my Onix system. On the contrary, I felt that where the Chord/Tetris system provided the full flavor of audio nirvana, my sub-$1,900 Onix system gave me a very good taste of it. AV123's 30 day trial period won't give one the complete benefit of experiencing a full system burn-in, but if one is serious about pursuing a revealing and musical system on a limited budget, this package combines some excellent component matching and synergy.
