Very good, thank you. I will report my findings. FYI, I am using a quality Audioquest USB cable. One more question... is there any reason for me to believe that such a set-up would not work in Mac OS X on a Macbook Pro?

  This is some really interesting info, thank you. I think I'm going to purchase the isolator board from Circuits@home and try it with the gen 2 USB card. Question... how would you suggest I power the board?? Keeping cost in mind, what kind/quality wall wart might be best?? Is something like a...

Quote:   That's a revision of the original board. The giveaway is the presence of four red, square-shaped film caps on the old boards. All revisions of the original board have them. The uber board is direct DC coupled which eliminates the need for those caps in the signal path. 

After a couple of weeks burning in the new components and listening to the upgraded A5+'s I figured it's time to offer some impressions and post a brief recap. So, here goes...   Each of the little mods detailed in Tim's directions was implemented on my A5+'s (minus the pure aesthetic...

Installed my uber board two days ago. Was pleased to find out that my bifrost, purchased in February this year, already had the newer USB board installed. Anyways, the über analog board is a sweet upgrade. Improved sound quality in my system across the board, particularly in regards to bass...

Quote:   My Uber analog card is due to arrive Monday. Excited by all the positive feedback!   Anybody notice a sonic difference with the new USB card??? I only went with the new analog card, for now at least.

Problem solved!!! The amp is working as it should and I'm now almost done reassembling the enclosures. This has been quite the learning experience...   Once I'm completely finished and the speakers are up on my wall I'll perform due diligence and post my impressions. From what I've already...

Not sure who's listening, but... progress!! I'm getting clean amplified music. I had to re-do all of my clumsy work on the board but it worked. However the right channel is louder than the left... significantly so. I swapped the drivers and crossovers and I reversed all the external cabling. Got...

Been a while... so finally, after a lengthy shipping ordeal, I received the resistors in the mail. I installed it carefully, tested it and reassembled the amp to see if my problem was solved... but still no good sound. However, this time I could hear music coming through but only with the volume...

Ah, thanks so much. I don't know how I got such an errant reading but I'm glad that you confirmed the value for me. I'm going to order some from mouser and just be done with it.    Also decided to try the wall mounts. I can also reclaim some surface area on my dresser by mounting the...

I don't need to, I choose to. i'm not that crazy!! Plus it makes my woman happy (we live together.) It's easy to do with the hollow wall that my TV hangs on.  I used to use foam but, with it being so soft, the weight of the cables attached left speaker, along with the heat sink, would cause it...

I've considered using wall mounts, I'm still considering it. But that would require running all the relevant cables behind the wall in my den. I'm a bit OCD when it comes to equipment and wiring looking clean. Cords and cables hanging all over drives me nuts and my girlfriend doesn't like it, so...

The volume/LED cable is intact and I put some hot glue on there.    I cleaned up the resistor area with some isopropal and it's now nice and clean. Well, not nice but very clean. It does look a whole lot better than it did in the photo I posted. Should be workable.    Thank you for...

The large difference in values is what I'm concerned about. Sorry, just trying to be careful. Too careful I guess. Wow, that's awfully generous of you to check that resistor for me. Man you must be getting sick of dealing with me at this point I really really appreciate you doing that. Very...

OK, I can do that. Question... in the case that my ohm reading was wrong, would having the wrong value resistor there (22K vs. 2.2K) result in serious damage or inability for the amp to function properly?? Perhaps I'm being paranoid here, second guessing my ohm reading because all the other...
