Hi Bud,
Could use the BHA-1 with the 4b and lose the (second) preamp.
My guess would be that the sound would equal the 135b.
Cheers,
Bob
Bob,
I used to own a BP-17 and I know that the BHA-1 can't match it as a preamp. It doesn't have remote control, it doesn't have the versatility, it doesn't sound as good as a preamp, etc. I've done an apples to apples comparison both with the BP-17 and the BP-26 compared to the BHA-1. IMHO, the preamps can't be replaced by the BHA-1.
I also need to downsize space and the 4B now has to sit behind a big screen TV while the B135 would fit on a shelf under the TV or in my current equipment cabinet.
I just ordered a Cardas Clear Light headphone cable for my HD-800's. This cable is single ended and will work with a preamp as well as the BHA-1. It won't sound as good as my Cardas Clear balanced headphone cable but it's more versatile and plugged into the B135 would allow me to vary the volume with my remote.
I'm also taking into account the complexity of dealing with this gear if something should happen to me. I have a nephew who could really use the B135. Dealing with the 4B is out of the question even for my nephew not to mention my wife.
I really don't need the money but I would recoup a bit of it if I made the change.
Bud
