pelliot gave me a heads-up which led me to download the attached...the $60k Altair preamp circuit is by John Curl(?) I think.

Quoted from their description..."Instead of the mechanical potentiometer found in most high-end preamps, the Altair uses optically controlled resistors that can be adjusted to an accuracy of 0.1 dB. To maintain the Altair’s perfect positive/negative signal balance and left/right channel balance in all operating conditions, we use 48 of these resistors—an expensive but undeniably superior design."

Dartzeel apparently uses 100 ldrs. Is that per channel or total I don't know. Have heard it runs around 27000.

Aaahh, speculations abound...here's mine. Simple math reveals 48 LDRs = (4 RCA inputs x 4 LDRs) + (4 XLR inputs x 8 LDRs). Processor control is switched to each input...

Just doesn't make sense to use an individual attenuator for each source. That's why I subscribe to the parallel ldr theory. Either way I bet it sounds great.

A golden nugget of inspiration again from NP...I have some ideas and will try to develop something using the Warpspeed.

Advantages are we can mix and match different design/gain power amps for passive bi-amping the top and bottom; and adjust top/bottom levels to our taste and room requirements. Might also be a good partner to the B5 for active bi-amping...

I received my kit last week and have been busy looking for the perfect enclosure.

Meanwhile, I have a question about batteries. If I was to use a 12v 10ah sealed lead acid (like Dodd's use) would there be any risk of over current to my Warpspeed??? Would some kind of current-limiting be necessary???

Another question... possibly off-topic

What is the reason that some of the enclosures pictured in have such tall feet???

Thanks,

Hi Ray, the W'squid has current limiting...but long before it kicks in, with a high current fault the optos would be long gone to semiconductor heaven...they'd blow like a fuse and open the circuit.

The feet...it was just the look and feel (and some damping) I was going for. In my own little imagination, seen from the side the chassis looks like a silver-headed black panther poised to lunge...

So, are you saying I should stick with the 16 alkaline D-Cell solution???

Thanks,
