Man, I wish I had $3500 lying around. I could have a couple of new computers!

Oh yeah, amp...

100 microvolts of DC offset is spectacularly impressive particularly for a channel that I assume was operating at half the rated maximum power (700W) when this measurement was taken! I'd hate to be the engineer that is responsible for mainting this offset during production. Tom Cumberland is even more of a "slave driver" than I am .

I could be dead wrong but I think your estimate of 10 to 20 times for most manufacturers is low. I would think that 15mV (150 times more) is a respectable figure that should not cause any audible speaker non-linearity.

This should certainly help to make any speaker more efficient and full sounding. Nice job.

Just re-read my post and realized (again) that I need to pay more attention when I am typing. I meant to say that I assume the channel was playing at 700W (ie. getting warmed up) prior to turning off the source and taking the measurement.

For the Axiom A1400-8, the DC offset is truly tiny, approximately 0.0001 volt--that's one-ten-thousandth of a volt, a fraction of the value that many conventional amplifiers often exhibit.




Needs more cowbell.

Seriously, are you guys saving the worst specs for last or something?

Hi Mojo,

Thanks. I decided to err on the side of conservatism in estimating the typical level of DC offset of other amplifiers.

Hi all,

The cutoff date for pre-ordering the new Axiom A1400-8 amplifier has been extended to July 31st.

And it's going to ship in mid-August now? Ouch!

It's a good thing, really. That's at least one more paycheck to create some breathing room.

No kiddin.... JC just confirmed that I can buy this thing on the lay-a-way plan. That pesky feller Robb owes me a beer. He cost me three grand putting that idea in my head.

Losing $3000 because of Robb means you're being Robbed blind, and him buying you beer afterward means you're being Robbed blind drunk.

mdrew...

You can feel free to thank ME with a 6 pack! I know you're in the oil patch, even tho its slower right now, you will be able to pay off that amp with 6 days work, so stop whining to me about it! :P
