Generally speaking, speakers with specs like that are going to thirst for an amplifier with a really robust power source. This doesn't mean lots of watts but, rather, an outstanding ability to deliver current when needed. If you go SS, I personally would not consider anything under a power rating of, at least, 100 watts both channels driven into 8 Ohms (rms) that cannot double that into 4 Ohms. Will your speakers sound good with less? Sure, but they won't be giving you everything they were designed to deliver. It would be like putting regular in a Ferrari Testarossa. On the tube side, there are many good choices. However, look for something with robust power supply. Good luck!
Integrated amp recommendation
I recently bought a used pair of Swiss-made Piega p4L MKII floor-standing speakers. I am looking for a two-channel integrated amp to pair with them. Budget: $1,000.
Among the stated speaker specs: applied power rating 20-200 watts, sensitivity 89 db, 4 ohms impedance and frequency response 38 Hz-50 kHz. To me, the speakers’ sound can be described as natural, detailed and transparent, not aggressive and maybe slightly lacking in bass. The room is 12 x 20, carpeted but relatively bare. I listen primarily to classic rock, classic jazz and classical. I use a Bluesound Node 2i music streamer and CDs. Bluetooth would be nice but not essential.
Thank you for any assistance.
