Hi Ralf,
Glad you liked the BHA-1 
I might suggest getting the unit with the built in power supply though. There is no difference in performance between the external and internal supply versions and having the internal supply makes it so much more convient to move from location to location and now that you can use it as a preamp even more flexibility. Not to mention resale value.

Hi James,
For me, the headphone amplifier is the logical extension of the basic unit BP-26, just like the phone amp PB-1.5 or BDA-1/-2.
From today's perspective, I'm not going to separate the headphone amp from this chain.
In my view, the external BHA-1 eliminates the only weak point of the BP-26.
Your objection to the higher resale value is absolutely correct. But in my case I do not speculate with the device. I only want to enjoy the perfect sound of the music. The BHA-1 gives me the possibility and this for many years
The Bryston motto "Music for a Generation" is not just a clever ad copy, this is the core statement of your products. I would not buy a product with a short lifetime or short useful life. What counts is perfect sound and long-lasting quality. It takes a long time until I decide to buy one, then I am also sure that this is exactly what I will use in the coming years.
Ralf
