That's a really tough price bracket to be successful/competetive in. I aplaud your ambition, and I hope it returns what you hope.
It's a lot of money but a lot of personal time and effort has gone into this - and given the price of the equivalent from the usual suspects it's surprisingly good value!
I have no doubts about the amount of effort or energy you have put into the amp, I certainly understand that aspect! Like I say, I hope you do very well with it. |

I cant remember when I first heard about these. Must have been 5 years ago? Please correct me. So, yep a lot of time has gone into them.

2019 was when I first posted about them, so around 3 years (though 2 if you don't count 2020 which was awful!)

Keep in mind that developing this was slotted between building new amps, repairs, amp rebuilds and countless other bits and pieces so it's not just been a solid 3 year design effort!

Ahhhh! Time goes by quickly. I thought it was longer than 3 years.

An interesting offshoot from the development of this amp is a deeper insight into the mathematics of distortion reduction - which can apply to all amplifiers. Performance gains are hard won with valve amps, but with solid state it all suddenly becomes much easier - and the insights apply directly here too. A composite amp with THD at -120dB or lower becomes attainable, something for the future....

Will do - I've not even seen any of it myself yet, it went straight from the sheet metal place to powder coat, I am excited!

Monoblocks indeed! They'll look better with the handles once they arrive.

Does this only take banana plugs, or does it come with binding posts?

Does this only take banana plugs, or does it come with binding posts? I consciously went with banana plugs (at the "standard" 3/4" pitch) to keep the rear panel as flush as possible - a heavy amp with binding posts poking out the back (especially just the one pair to the side) can be a bit awkward especially for packaging and shipping. Hence the D-Shell RCA for the unbalanced input too - it doesn't protrude. There is method in the madness! |
