after reading the thread about classdaudio amps... thanks jtwrace, I contacted Tom at ClassDaudio. In his reply to me, he also shared the following information and ask me to share it on audiocircle... so here it is:
Hi Mike,
To try to make this a more easy answer... today or tomorrow we are introducing our new "Super D Series" amps with balanced input and adjustable gain. In about a week, we have a version of this amp coming out with balanced input, adjustable gain, but... also can drive loads below 1.5 ohm. This amp is rated at 500 W RMS per channel at 2 ohm! Of course, this new series of amps is more expensive than our other series and on average about $100.00 per amp more. The 500W into 2 ohm is even a little more expensive.
These new amps from us have the finest balanced inputs available anywhere on the planet, and can also take input voltages up to 20 volts. Input impedance on the Super D's is 47k. They also have external adjustable gain controls (work like volume controls). Also, no more soldering for external LED's, switch, or gain controls, as I have incorporated Molex type connectors for all of these, and also include the connectors with wires attached to make things even easier. Larger and better cooling heatsink too. These amps are the same width, but 1" longer than our other IR based amps.
I believe we have answered all requests and comments from our customers with this new amp. I also believe it will possibly prove to be one of the finest audio amplifiers available today and at any price.
I will try to get a news letter out with the new amps in the next few days. Things have been very busy for me here with work from early morning to about 1:00 in the morning 7 days a week, so I might be a little late getting it out. If you're in the Audiocircle.com forum, maybe you can pass on this information for me?
Please let me know if I can be more help.
Thanks,
Tom
