with all the progession in DAC technology etc, I'm guessing we are getting close to a point of dimishing returns on investment, etc.....anyway, listening to vinyl is always as feasible in my home office and I was wondering where a good jumping off point would be in terms of purchasing my first DAC.....I've got great pwoer amps and tube pre amps as well but would like to eventually be able to hook up a DAC to stream and listen to music when I don't have the luxury to get up and down to flip records and stax o wax, etc......anyway, where is it nowadays that we start to hit the laws od diminishing returns with DACS....or where can I get my best bank for my buck. Especially with my aikido and singel eneded tube amps, etc....I'd love to have the luxury to stream from my computer or phone and still get great audio quality....I know its hard to beat the emotioanlly connection with vinyl, etc....but how much shoul I be looking to spend on a DAC to amke the most of my oldschool amplifiers, etc.
