I listen to a lot of 'Spotify free service' . . . they offer a 'premium service' for £9.99. Saying no ads, but the main thing that interests me is better quality, streamed at 320kbps. As I use the signal direct from computer USB to DAC to Amplifier and a classic 2 channel set up. Is the 'better quality' an an vantage in this type of set up? A lot of the music I choose is 50's, 60's and selected 80's - 90's, I wonder if the old recordings will benefit? Although some are superb IMHO . . . with the simple technology of the time, multi tracking is limited allowing better access to the real performance? CJS
