Default ad 1865 best DAC

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.

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.

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)
