Digital Guru's -- Please suggest a DAC - Page 4

Hi Jared,

If you want to go the SE route, then any common 1:1 line-level transformer should do the trick, and then you can run it straight across the output and omit the caps. I have yet to try it, but I would imagine it'll work quite well. It will certainly be much better than the resistor/transformer setups I've seen used elsewhere.

Anyone more familiar with transformer coupled DACs have any suggestions? What do people usually use here?

Unfortunately, the cost of a pair of transformers will probably blow you're budget, but what are budgets for if not to be blown?

Cheers,
Owen

it does work quite well like that, I have been using a pair of O-netics (about 150-200 for the pair) connected directly to the dac and directly to the outputs. havent tried SE just balanced, but doesnt matter with transformers, nothing else is needed

Yea, the Buffalo ($250) + PS ($40) + TOSlink module ($15) + decent transformers ($150) + I/V stage ($50?) is just more than I want to spend.

Do you think your I/V stage would work with the Twisted Pear COD? That would bring the price down to more reasonable levels for me. How about the Twisted Pear Opus (a voltage output chip) direct to transformers?

Don't forget an enclosure in your pricing too...
