Wow, thanks for taking the time to answer. The T&A HV amp is within reach and looks good, but the HV pre is tough to justify at +$30k for a blue collar guy like me.
My only Krell was the kav 300il and while it's not the same level as the xd stuff it was the only piece that could tame my old kef R105\3's so I'm not surprised you like them. My problem with krell was the 575 monoblocks I heard in a fellow audiophile's home driving the salon 2's and the pairing was rough. The H590 is close but i'm starting to notice some midrange congestion I hadn't previously on some recordings, I also recently joined qubuz so it's possible the difference is im the recordings, that I can work out myself. Hegel finally updated the H30 with the H30I if I can find 1, that still leaves me shopping a dac preamp.
Thank you for your patient reply, I'm leaning towards the T&A if I can get a decent price.
