It looks like the back end of an old Electrolux vacuum.

I would have never thought of that one...

I have had this exact discussion with Tom, and there will be a 250 watts into 8 Super D series module... he's waiting on some parts to build the modules and to finish up testing. He said he should have them in a couple of weeks.

Website show SDS-258 250 x 2 into 8 as in stock.

Hmmmm what have we here?

End cap from 1940's Electrolux vacuum, small brass doorknob mounted in a donut of lexan which was then mounted in the hole where the hose once attached. When I ordered the kit, I asked Tom to please mount the LEDs on the bottom of the power supply board so they would shine out the front. Makes me smile every time I look at it. Was actually using Tik-Tok as a model. While scouring the internet for pictures of robots I found a reference to 'Moloch' from the movie Metropolis. One modern translation of the word is "Person or thing which demands or requires costly sacrifices" Pretty accurate description of this audio hobby isn't it?
Thanks for all the kind words.

So how did I know that, born in the 1940's and my mom had one.

Like I said before, I would have never thought of that one!

Take me to you leader. I love it!

If I had to vote here and now on the coolest case for D-amp kit, this would be IT!

P.S
looking strictly from creative point of view.

Well I trepidatiously sold my 60 watt amp cause always in the back of my mind i was fustrated since i fell prey to the 4ohm vs 8ohm confusion. I had always wanted 120 wpc @8ohm from the start.
I had heard more than once that most perferred the sound of the 60 watt amp and i also loved everything about it. I very much think that the 60 watt board with larger power supply is a very special combo and boldly reccomend it. I was very aprehensive switching to the 250 board not knowing if it would measue up.

I decided to try the 250 wpc SuperD amp and i am pleased with the results. I confer with Steve about the increased imaging and slightly overall better sound. But i do have two things working against me, i switched to increased power and i am going off memory. I feel like i have better and tighter bass response and the new board seems to have a better control of the music. This is my first impession and i only have an hr or two on the amp. Once again i highly reccomend the ClassD amps and the new series is also a winner.

A work in progress, my Parts express order was rescheduled

Hope you will post other perceptions and comparisons of the two amps as you can. Thanks!

This is some info Tom sent me on the new inputs. It mentions single ended inputs also take advantage of the technology, which is what Steve and I both were testing with. I cant help but wonder if balanced improves even more.

Quote

“The patented InGenius balanced line receivers overcome a serious limitation of conventional balanced input stages: poor common mode rejection in real-world applications. While conventional input stages measure well in the lab and perform well on paper, they fail to live up to their CMRR specs when fed from even slightly unbalanced source impedances — a common situation in almost any pro sound environment. This is because conventional stages have low common-mode input impedance, which interacts with imbalances in source impedance to unbalance common-mode signals, making them indistinguishable from desired, balanced signals. Developed by Bill Whitlock of Jensen Transformers, the patented InGenius input stage uses clever bootstrapping to raise its common-mode input impedance into the megohm range without the noise penalty from the obvious solution of using high-valued resistors. Like transformers, InGenius line receivers maintain their high CMRR over a wide range of source impedance imbalances — even when fed from single-ended sources. But unlike transformers, these wide bandwidth solid state devices offer dc-coupling, low distortion and transparent sound”

Okay, here is mine. A good audio friend built it for me. He builds his own tube equipment. He put a volume pot on for me as well. He still has it and is running it in a bit. I'll get it in my system in another week or so and let yall know what I think. Isn't that a sweet wood front panel!

Nick77 · « **Reply #1093 on:** 2 Apr 2010, 03:56 pm »

Wow! He does very meticulous work. Awesome!

roymail · « **Reply #1094 on:** 2 Apr 2010, 04:04 pm »

Is that the 120/4, 60/8 ohm amp?

Let us know how it sounds with the VC.

Beautiful job of wiring, and love the front panel.

Thanks!

My SuperD has shipped...Geez, now I have one of each.

My aluminum case and some amp boards will be very happy together.

I'll make sure I pass along the compliments. He does build some beautiful looking AND sounding gear and even does the woodwork. It is the 120 wpc model that started this thread but is the latest version (according to Tom).

That is a thing of beauty. It would be really cool if you could provide more details on the build such as specifics on the case, external parts usage, etc. At any rate - compliments!

Hey!

pardales, that looks nice. The wood front panel looks great!

Take care,

I am interested in buying a 250 x 2 amp board if someone is upgrading.
Send me a pm with info.
