I have a combined 2 channel / 7.5 HT setup. The two channel system consists of a nice pair of monoblocks for my main speakers, and a preamp with HTBP. The center and surrounds are powered by a 5 channel amp and I use a Marantz HT processor. Your center channel is the most important channel for home theater, that's where most of the dialogue comes from. Getting a better amp for 2 channel is a good idea. Are you only running three channels for HT? If so, consider a monoblock for the center. If you have surround speakers, the Krell is probably fine.
2 channel + HT suggestions
Hi All - I’m limited to one room for my set up so I needed to solve for two channel and HT. For this reason I went with a krell theatre 7 HD for my amp, which I now know is the weak link. The rest of my system includes PS Audio BHK pre (ht pass through) PS Audio DSD, Roon into Matrix into DSD, B&W 805 D3 + Rel sub.
i’m fairly set on a pass labs 250.8, which gives me optionality to scale a 2 channel room later with larger speakers, but for the current set up I then need to solve for the center channel. I’m only running 3 channels so the Krell is useless. What are your thoughts on powering the center channel?
