I'm in Toledo, half way back to Bozeman after the National Meet, so I can't really make a long post here, but I know if I don't post soon TheSloth will explode, so I thought I'd announce now and give him some space to post his thoughts.
We did, in a rather low key way, announce the new amplifier electronics at the Nat'l meet. After all my posts defending the various compromises that make an integrated chip solution for output power stages, I am now happy to announce that ALL HeadRoom amps are now shipping a descrete output power amp stage design. Our new modules output is a Diamond Buffer design with our own mix of adjustments to suit. I will soon post the details of the differences between the modules, but suffice it to say we are very pleased with the results. Basically, the modules are the same input and crossfeed stage as previous with the new output stage. One of the nice things about the Diamond buffer design is that you can just "dial in" how much bias current you want (how far into class-A you want to force the output stage) so the Micro module has a lower current draw than the Desktop. The Home forces all the pre-amp stages into class-A. The Max uses 627s, of course, with some SWEET output transistors. (I'll fill in with tranny numbers when I get back.)
Additionally, we have LOWERED the price of the module upgrades; our birthing management systems have allowed us to understand our costs better and we found we could lower the cost of this service.
Well, Andrew is jumping up and down to get going and start the next leg of the drive so I have to go (Fargo must have a strange attraction for him) so I'll let The Sloth fill in a few blanks on the sound for a couple of days.
