Hello, I've been using a budget Sherwood amp that I bought 25 years ago but due to a house refurbishment and am looking to move it to a bedroom and buy a replacement main amp for the dining room. Money is tight - I could probably stretch to around £100 so am looking on ebay. When I bought my first system a friend had a NAD 3020i and I reckon I could find one in budget on ebay. So my question is, would I be better off trying to get a newer amp, perhaps something from Cambridge audio, or a Rotel ra-01? The speakers are Eltax monitor iii (probably 15 years old) that will be wall mounted and the source will be a spotify subscription through a chromecast audio. Thanks.
