A few steps down for 2 channel? ..What is your 2 channel set-up?I am on my 3rd complete HT upgrade since I got into the hobby in 1998.
I'd definately require a center with the PSD-2002 to maintain the voicing across the front so panning is smooth.
I suppose I am going to have to hear my Stage 4 Pis first but if I like them I would be interested in a 3 or 4 Pi for center use and maybe some One Pis for surround duty.
First and foremost though these Stage 4 Pis must excel in 2 channel as well as HT because I cannot afford 2 systems.
I have been thru at least 7 or 8 pairs of main speakers since I got into this hobby so I pretty much expect each upgrade to at least be a lateral move..but I sort of am expecting an upward move with these Pis.
The link is some pics of my HT which is just my spare bedroom. :-)
