I got a few queries about the Denon mini I use. Used, if shipped from Europe, it will cost you approx Rs 150000. I will not tell people to blindly buy it. You may end up being very disappointed. As I said before it works well with certain vintage speakers. It’s not too fussy about isolation, but a good stand will benefit it a wee bit. It comes with a captive power cord. Do not change it. Everything in that unit is optimised. It doesn’t allow any tweaking. At best you can try some isolation and provide it clean power.
Also wanted to add that this is not a vintage amp. It’s from early 2000. It’s very neutral. Doesn’t add any body. It’s far away from the vintage sound that you get from the older models of Sansui, Luxman, etc
