pre amps with HT bypass


I need to use the system as a dual system. Two channel and HT, so as I rebuild it I want to go to pre amp with bypass. I notice a couple have this feature. Can folks help me make up a list. The speakers I am using are maggies 1.6.

I am going to also purchase a power amp as everyone is saying that the NAD 975 at 140 watts is not doing it. I am thinking a Bel Canto 1000/500 or Wyred for sound, perhaps Nuforce

Any help will be welcome.

James63 you hit the nail on the head. That is what started me down this road. The Magnepans are just a touch bright in my room with my set up. That is the reason to try the tube pre. And I am going to listen a lot before buying. So it could still a solid state.
I owned 1.6's for several years and at one point I was using a Modwright 9.0SE,HT bypass,paired with ss amp.Very good synergy.
