Perhaps, I missed this, but is the black part of the chassis going to be a brushed black or a polished black? Just curious....

Looks fantastic!! can't wait to see the final product.

It'll be grained (brushed) and black anodized.

Here something in Marantz's Reference series style [with IPodPJ's volume knob]:

Mouth-watering.

Internal fuses? Or is that the fused Furutech IEC inlet?

Neutrik Powercons are just lovely connectors.

Steve must be having a conniption over the two three pin XLR's, ha!

Really nice work, Phil and Steve.

Not sure yet. Phil's been vacillating.

That was the deal. I agreed to build it with dual three pin XLRs, and in exchange, he agreed to put up with my bitching about it.

He's a bit bummed that I refused to allow my name to be put on the amp because of that, but I'm sure he'll get over it.

Thanks, though it's a bit early to be giving me any compliments. All I've done so far is stuff and solder the boards. This is all Phil's work. Wait'll I actually get this thing built, then you can heap all the compliments or criticisms on it you want.

Thanks Lee.
The IEC is the newer FI-03 with the fuse holder and solder points. The FI-09 would be great if we were using 12 gauge cable but it isn't necessary for this, and has no fuse holder. It was a bitch drawing the IEC since I had no head-on photos to work from. It isn't exact like all the other connectors and jacks are, but is pretty darn close. It seems I forgot to put screws on it. I didn't leave my office until 3:30 this morning. I think I have somewhere around 25 - 30 hours into those drawings, partly because I was trying so many different layouts.

Steve has his work cut out for him. I've proposed quite a few challenges like a custom relay for the input selection LEDs, LED in the volume knob, passive I/V stage for the current input -- all of which may be easy for him but still require the logistics of doing it cleanly -- while keeping the wires in a nice arrangement. What good would a project like this be if only the outside looked good? (I know you and Josh share that belief.) Steve will do a dynamite job on the guts, that I have no doubt. He is also translating my Illustrator files to CAD drawings for the machining of the front and rear plates. The front panel is 5/8" thick.

I figured as much. You are going to steal my "audio curmudgeon" title from me.

Peace,

Good inlet, easy to use and one less hole for the fuse holder for the CNC to drill.

When you get a chance, send a rhodium plated cryo'd FI-03 over to Steve. I'll send you his address.

Thanks!

very nice work guys!! well at least so far case design is not to be underestimated. re the inlets. I have been umming and ahhing about my buffalo32 inlet. I have both the FI-03 (rhodium) and FI-09 (also rhodium) here as well as hifituning fuses and a cryo silver fuse holder (an experiment), I decided in the end to hardwire the fuse to the AC line, power is pretty decent here and I have a conditioner anyway and noi aversion to soldering in a new one if I must. I am using 12AWG neotech copper for AC, so I really had no choice is I wanted to keep that option.

whats the model number on those DC jacks?? i'm very interested to see the current mode implementation. such a pity there arent more choices for 4 pin XLR, I have it as an option, but cant leave off 2 x 3 pin unless I really want to limit the cables and headphones that can use the dac/amp without an adapter. I can only immagine the hard time you got

Thanks!

Which do you prefer, the FI-03 or the FI-09? I'm still undecided and would like to use the best one. Power cords are very important to me as I feel they have a substantial impact on the sound. Not to mention, I have big cords that weigh around 7 lbs (3.18 kilograms).

The DC plugs I am using are the Neutrik PowerCon 20 amp. The current plugs are some cheapos from China that Audio-gd uses on all their gear. Since I am using an Audio-gd Reference One DAC, I may include a passive I/V network inside the Beta22. If I decide not to after trial with a custom current-to-voltage cable, I will make an active I/V stage in a separate chassis.
