Builiding system around NOS dac


I have a NOS dac and I really love the sound (I discovered that I am allergic to fast sound or however you wish to describe it). I have head phones now and want to build a speaker sytem with this or another NOS dac. I have been reading about Harbeths and they sound great (have not heard them yet but dealer is thankfully 2 hours away). I know NOS dacs need careful system matching and was wondering if anyone could give me some info on matching components (want ss amp and have blue circle pre amp that I like) like fast speakers (Physics), or harbeths, class D or A etc?

Thanks

The most important thing with a NOS DAC is to feed it a really low jitter digital signal. Most Transports will not do.

Also, if the output is direct from a stack of 1543's through a signal coupling capacitor or the like, then driving a high-capacitance cable is potentially problematic. If you want the best performance from it, use low-cap cable and drive high-impedance (50K ohms+) input.

Hi Steve. What is a 1543?
The TDA-1543 is a DAC chip that is sometimes used in NOS DAC designs.
