I figured out I do not want any flavor to the sound from a preamp. I also want complete silence from the preamp (deep space silence) with an incredible volume control and inputs for my sources. That is what the HPA4/LA4 gives.
My current AHB2 amp also has no flavor but in the future, now that I have new speakers, I am looking to add something like the Luxman m900u or the CODA #8 or #16 to pair with the HPA4. I will rotate 2 amps with the HPA4 to waste my time.
I would love to hear folks who have tried this pre-amp and compared it to others as I have.
