No assumptions Colin and I'm perfectly aware it's a Forum. Moreover a Forum with rules you have broken. One rule is not to comment on kit you have not heard and if you look back at your posts you commented on my modded Audio Note Dac which you cannot possibly have heard.
Re DACs to listen to, I would of course recommend the Wavelength Proton (the others use valve output stages /have separate psus so you may or may not wish for that style of DAC).
The problem is Wavelength is not currently available in the UK. But you can easily audition other members of the 'Wavelength family' i.e using the designer's patented Streamlength software. This would lead you to try the Audioquest Dragonfly and the Halide Bridge DAC. The first of these is designed completely by the Proton's designer.But there are many more out there.
I have not heard these particular bits of kit but magazine reviews indicate the same type of sound as I get from my Proton. Full bodied, 'analogue' sounding, with huge dynamics and great details from top to bottom frequency. And by 'analogue' I mean non tiring for extended listening and able to perform equally well across all types of music rather than bland.
As always, I caveat the sound I get as being in my system, therefore not necessarily reflecting how it might sound in yours. I also use an ultra low noise psu, so therefore so along with the Proton's batteries supplying juice for the critical bits, I have no reliance or connection at all to the computer's noisy psu.
Go listen and let us know how you get on!
