Wow. Interesting setup you have there. I guess sound is more important than aesthetics to you. I'm sort of one to leave equipment strewn around, myself. However, if I left it open like that, my dog would destroy it. I think you should post that in the 'ugly amp' thread if you haven't already . By the way, I've never heard any OB speakers before. How do they sound compared to sealed/ported/PR?

The following picture might seem distributing to some people .


First off, it actualy works and I think it sounds pretty good.

The DAC (the stuff below the TV and in the shoebox) was the first I built from scratch. Currently it is a 2 X 1541S1 NOS using Elso's async reclocking, CS8412. I/V is done by opa627 followed by a buf634.

The speakers are fostex FE206E OB (they have moved on to some larger spiral shaped baffels). For bass I use JBL2225 in former bas reflex boxes now seal. They are soon gonna be OB too. (Yes I know not the perfect drivers for OB, but I want to try anyway)

In order to get a decent response from the JBL they are getting a 12db boost, which accorid to my calculations should make them roll off at 50 hz
XO: Highpass is a 6 db line level XO in front of an opa627 with gain of 1. Lowpass starts with my bass boost and the XO is the ASHLY.

The amps are 4 lm3886, each with a 300VA and 2 X 1000 uf silmic. Next project for them are regulation and then a decent box!

And if I haven't given you any reason to flame my setup: The total count of regulators is 37.... all lm317 and lm337

Merry Christmas

Yes and no. But when I have build something I want results fast, and most of the stuff is still prototypes with lots of changes on the drawing board.

Only the amps will get boxes in the near future.

I'm sort of one to leave equipment strewn around, myself. However, if I left it open like that, my dog would destroy it.

All my pets are locked any. Last time they got near my setup, my dac suffered 4 cut wires, lucky for the dac and the pet, that it wasn't on.

I think you should post that in the 'ugly amp' thread if you haven't already.

I will, the amps have some very unusual features

By the way, I've never heard any OB speakers before. How do they sound compared to sealed/ported/PR?

I can't say anything about the bass department yet, but for the midrange more air, more detail. I'm never going to cage a midrange again

I've separated music from HT and were I to do it over again I'd go with a front projector. I haven't made it pretty yet but it sounds great. The center channel is still in development, the black column on the right is a Shiva 'tube, on the left a vented Tempest, my Isa mains, Pyle Pro amp, BFD, JVC 5.1 receiver, Toshiba DVD, and Toshiba 65" HDTV and Dish receiver.

Hi Lieven;

Are those JBL 4435's in the center of the picture? And on the left L250 WX's ? Circa 1981 or 1982 ?
