Jolida integrated amps are not very expensive and are new. Unless you buy a very well taken care of "vintage" unit you may find yourself spending money to keep it functional. All of these things have parts with finite life spans. The Jolida integrateds are also very nice looking. As with all gear you are going to want to match the components carefully. A Jolida JD 202 with a pair of Kef speakers would be an affordable set-up that would work well. The Kef speakers are usually efficent (92dB or higher in most cases) and are not $$$.
Good luck!
