T+A DAC 200 or WEISS 501

My choice would be neither because they both have pre-amps and the Weiss has a renderer, I would choose a pure DAC without anything else.

The reasons to choose the Weiss against the T200 come down to size and it's 4ch processing which I believe can be configured as a Hi & Low crossover.

It hosts a plethora of algos that are going to make your digital syrupy and completely coloured and untrue to the recording. Great if that's how you roll.

Beware it comes in MK1 & MK2 versions MK1 uses a really old ESS chip whilst the MK2 uses the ESS 9038 Pro. Previous top ESS chip, current is 9039 Pro.

I haven't heard the T200 so I will reserve judgement but it lacks appeal because it's not a pure DAC.

@lordmelton I do not need a pre amp feature because of the integrated amp I use II do need a pure DAC only but am not sure what  should choose for a transparent and dense musical bliss.

@jasbirnandra The T200 comes very highly recommend by many here as the best value DAC under $15k.

Much depends on your system of course and you need a demo.
