IF its leaning a bit towards the analytical currently, ARC should be a very good choice to nudge it properly in the right direction.
I use an arc sp16 with the same amps and it is a match made made in heaven, hard to beat IMHO. Other recent ARC pre-amps I have heard ( I think I heave heard the ref 3)sound similarly good and can likely only be even better in terms of frequency extension, dynamic headroom, etc. But frankly the sp16 is hard to fault on its own as well. Does require period tube replacement, 6 total, one premium tube with very low noise levels for the phono section specifically.
