Berkeley Alpha DAC vs Theta Gen VIII and stuff...

More ramblings of a madman...

So my search for the preamp has lead me here. Thanks to all who posted in my thread about the Spectral pre but i think i have narrowed it down to an odd pair, the 2 Dacs in the title. This arose from a long phone conversation yesterday with the guy who sort of mentored me in this whole audio mess. I had bounced the idea of the Spectral DMC 30SL i was ready to buy off of him and we had gone round and round about the options. A friend of his has some similar gear, WP's and the like, and had had that Spectral as well as the 30SS + the Spectral CD/DAC. He had also been searching for the right fit and came across the Berkeley Alpha Dac. His comments are strong but they mirror what Robert Harley stated in his TAS article, the BAD is better than the Spectral System...the DAC and the Pre...he has replaced all that Spectral gear with the BAD run directly to his amp. WOW! I am in. But...I must complicate this...If i am going to go the DAC/Pre combo route I might as well include the one I personally have always lusted after...the Theta Generation VIII. Ok...so now I have narrowed this down to the final 2, this is great progress. Help me drive this home fella's...

Has anyone compared these 2 fine devices? Anyone have experience with both that may help me close the door? It is not realistic to get them both here to do a listen, that is out. Gotta go on my gut and some input from the forum.

I suppose my first thought is the newer BAD is a better option given the progress in digital these days as well as the higher rez but the Theta is a classic sweet DAC which has been among the finest available for some time. It is also Theta, A company that seems to be a shell of itself since ATI got involved. Hmmmmm.

Whichever i chose will still be a challenge as neither has a solution for ht pass through. I will need to find some sort of switch at the amp or just change cables when I watch TV/Movies.

So this is where I stand. Input on these 2 devices, experience or comparison, greatly appreciated...

Rest of the system (for now!):

Krell FPB 600c
Wilson WP 7's
Logitech Transporter (will be the only source acting as tranport only)
MIT MH850 speaker cables
MIT MI350 CVT Proline Reference interconnects
MIT Oracle AC1 power cords
MIT ZStabalizerIII HG conditioner/filter/surge

HT stuff to pass through some how...

My home theater will pass through.

Worldcat- From the Theta website:

"8.Go into the Generation VIII Series 2 unit's setup menu and turn on RECLOCK for any high resolution digital sources (i.e. CD transport) to obtain the highest sound quality from those sources, or JITTER JAIL for any lower resolution digital sources (i.e. PC Sound card, DVR, SAT, etc.) to reduce the digital distortion from such sources. To do so, go to SETUP / 5 BUTTON / 2 BUTTON / LEVEL UP or LEVEL DOWN to select either JITTER JAIL (the factory default) or RECLOCK, for maximum sound quality."

It seems more detail and more focused soundstage in the re-clocking mode. Maybe not as much air as in the jitter jail to me and i think in the jitter jail mode its a little more involving. There is totally two different sounds. I like them both:).

All, thanks for your help here I have a Gen VIII series 2 and based on this discussion I changed from jitter jail to re-clocking. All I can say is WOW what a huge improvment in sound stage clarity and bass definition! This is a whole new and much improved sound from red book cd!

Worldcat/Fsarc/Ronv - Have you tried both the series 1 and 2? Were you able to tell the differences side-by-side, or in close time proximity to each other? I read the Serinus review, sounds great, but my dealer said he upgraded one, and the upgrade sounded more resolving, but he thought it may have been a case of resolution at the expense of musicality. But that was cold, with no beak-in, as it was a customer piece, and it went home with the customer after update.
