Good 2 channel premap with HT bypass

Looking for 2 channel preamp recommandaions with HT bypass. I read on Audiogon that there is no pre-pro out there that can match a good 2 channel preamp. I have been looking at an Arcam AV8 prepro, and Arcam states that in direct mode, DSP is turned off and the analog signal is passed unprocessed, with the power supply operating via a self-generating clock. Arcam states it is the best preamp they make. Still I would like options, my speakers are Heron i's, and I was told they tend to sound better with tube gear. One question, can I control the volume of the HT with just the prepro if I have an HT bypass in the preamp? I see Supratek has an HT bypass any others? My system may look something like this when done.
prepro = AV8 Arcam
Amp = eVo6 mono blocked into rears and CC 350 wpc 8 ohm
Amp = VTL or Rogue for the fronts
Preamp with HT bypass = Supratek or other
speakers = Heron i's fronts and bookshelf for rears, and sometype of matching sub.
dvd/cd player = right now it is a Sony from best buy. May upgrade player or buy a Electocompaniet DAC or other DAC as upgrade.
Maybe I will like the sound of the AV8, but hard to tell until I get it hooked up. I have auditioned it at a local dealer, but it sounded a little boxy. I think it's due to the speakers they are running them through. They were not the best. Thanks to all who respond to this thread.
