Looks nice for 400$, which is converted price, strong built, with a switching button which looks like famous "lounch missile" button in B action movies. Actor have to cut one of wires to stay alive, red or black, or yulong s gonna blow....

Number 16 Fs actually worries me, anyway, I think that guys from Romania, made better dac...rockna

But, I agree with audiodesign, ad 1865K is awesome, natural, punchy and had a plenty of detail. Worth every cent.

Anyone tried that AD1865 Rockna dac? And compared to the 24 bit upsampler from Rockna?

Has anyone heard the WM8741 from Wolfson Electronics?

128dB SNR in mono

Wow! great review.

I use a budget Cambridge Audio 640v2 (Mono WM8740's) and it's made me think the TDA1541A is getting a bit dated.

I replaced the electolytic coupling capacitors with films, decoupled the DACs with Oscons, replaced the 7805 that feeds the clock with a Pinkfish flea CLICK HERE and
used a LM1086/VBE to feed the 5v analogue supply to the DAC.

I'm really pleased with the results and i havn't touched the 78xx/79xx +/-15v supply to the opamps (NE5532)....Yet!

I'm going to build a basic LM1086/337 supply and when thats fitted, i will experiment with the opamps.

Clock upgrade in the Cambridge?

fatmarley · 8th November 2007, 09:28 PM

I didnt upgrade the clock because it looks like a good one. I replaced the 7805 fixed regulator with a pink flea and built a seperate PSU for it (Transformer, bridge rectifier and cap)

Hope to try the WM8741 in the next couple of weeks.
