Integrated Amplification: Devialet Expert Pro (size of a large laptop)
Sound quality is excellent. Will drive pretty much any speaker.
Speaker; Thats quite a personal choice, and there are great options that are manageable in terms of weight and move-ability, and that won’t break the bank.
Optional Streamer: Depends on your budget. I finally got a dedicated streamer and its very convenient. The DAC in the Devialet Expert Pro is superb and is superior to the streamer’s DAC, but its nice to have that option to use as a DAC also.
Turntable: As the Expert has a great phonostage, why not? Pick up a gently used Technics SL-xxx. I got a fantastic used SL-5300 for reasonable price that plays beautifully. If you want a killer phonostage for absurdly bargain price, just because, pick up a used Lehmann Black Cube. For $250’ish you can pick up an excellent gently used MM cartridge, such as the Clearaudio Performer V2. It makes music.
Power: Not one for power conditioners (I’ve been through 4). This fifth one though is the real deal, and for me, has really transformed the performance of the HiFi: Older generation PS Audio Powerplant Premier. Make sure you get one thats recently rebuilt / serviced, because after a decade of use some parts do give out.
I won’t get into interconnects because that’s a personal preference thing. But if you can spring for older non-knock-off Nordost SPM Reference (speaker and interconnect) the SPM is superb and VERY musically satisfying.
