It sounds like you’re in the market for an integrated amp - not a preamp, correct? Some clarification questions:
- Would you want one with a built in phono stage, or do you have an existing phono stage? What turntable and cartridge are you running?
- There are a growing number of good, streaming integrated amps out there nowadays. One of these could be an option OR you could opt for a separate streamer.
- Your quartets are quite sensitive at 98db and 8 ohms. So you won’t need a lot of wattage to make them sing.
- Tube or solid state or hybrid? The wattage output makes a difference based on which option. For example, 25 watts of good Class A tube power can be just as loud and full of presence as 100 watts of solid state. There are quite a lot of excellent options at your price range for each option!
