XA160.5 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.
