Speaker Interface
We go to a lot of trouble to make products reliable, and the failure rate of our amplifiers is very low. This is small comfort to the few, but take it easy and give us a call if you have problems.
People are interested in how long it takes for these amplifiers to break in. Depending on the resolution of the rest of your audio chain, you may or may not notice any break in of the amplifier beyond the first few hours of operation. You will very likely notice the difference in sonic character between cold and normal operating temperature over the first hour, so we recommend letting these amplifiers warm up before any serious listening.
This generation of amplifiers warms up faster and is more
The amplifier has a thermal cutout that will disconnect AC power if the temperature exceeds 75 degrees Centigrade. This thermal cutout should never occur in real life. This is a very rare occurrence, and would indicate a serious problem.
We have a general recommendation about interconnects, and speaker cables: They should cost less than the amplifier, and contain at least some conductive material. We have tried a lot of products and most work well, but as a practical matter we cannot make blanket recommendations as to your purchase of cables. Under all circumstances you should unplug power cords before changing signal cables…. you’ve been warned!
The amplifier is not sensitive to source interconnects. It is also not sensitive to radio frequency pickup, which allows some flexibility in choosing source interconnects without shields, though shields are usually a very good idea. For long runs balanced cables are highly recommended for their inherent rejection of noise.
We prefer speaker cables that are short and stout.
Fortunately this amplifier is not sensitive to the capacitive/inductive character of some of the specialty speaker cables, so feel free to experiment.
We have found that about 90 per cent of bad sounding cables are really bad sounding connections, and we recommend that attention be paid to cleanliness of electrical contact surfaces and proper connector fit.
