My interest is stereo music. specifically analogue music. I was very fascinated by the company Cadence from Pune. When I had previewed their valve amp and hybrid electrostat speakers 15 yrs ago I was very impressed. At that time I did not have that kind of budget. Now I am looking for them but can't find any one dealing with them. Are they still making the system? Is it worth going for pre owned system? I can find a few on OLX?
