XA60.5 Owner’s Manual
All the usual performance metrics - power, distortion, noise, input
impedance, damping factor and bandwidth have all been improved
in this latest generation. The power supplies are larger, with fast
rectifiers gating to larger capacitor banks. The increases in AC line
noise worldwide have been addressed with heavier EMI filtering
and dramatically quieter power transformers. In addition, through
improved biasing regulation, the circuits give much more consistent
performance under varying AC line voltages and over a variety of
ambient temperatures.
All this is very nice, but only if it improves your listening experience.
We listen very carefully and critically to our amplifiers with a wide
variety of associated equipment and we take our time with it.
Musical performance is most important, and is the basis of our
success over the years.
It’s true that we also value the other things. The design and
manufacturing decisions have to balance subjective performance
against reliability, cost, specs, and ego (in approximately that order).
That is why we make more than one amplifier, but all are built with
the same commitment to quality.
If you have purchased this amplifier, we thank you for your
confidence, and hope that you enjoy it for many years. If you have
any questions or comments, or if we can help you with your audio
system, pelase don’t hesitate to contact us.
