1) Bryston could have a "Headphone upgrade option" on the BP 26. Then a really good headphone amp could be added to the BP-26. Say a $400. option. It couldn't take up much space to add a few bits in there to upgrade the headphone out to 'really great' status. I own four headphone amps. one, The notorious 'exploding' Singlepower is even dangerous (which, actually, is why i bought it.. delicious.) From $250 Little Dot III to a TaDaC, then the SinglePower MPX3, and a Rudistor Rpx-33 II
2) a separate box (sized ala Bp-26/phono 1.5 with a power connection to the PS used by BP-26 and 1.5) that would be (analog only)TONE CONTROLS.
Most of you do not really remember tone controls. They worked, they were really nice, they did cool things. Then some audiophooles decided they did 'bad' things and did not want them. ALL the manufacturers of high end stuff dropped tone controls.
A separate QUALITY box, with a variety of options worthy of a Bryston product: Standard rotary tone controls,three: high, mid, bass. Defeatable of course.
a variable setting Loudness control with a knob, defeatable of course.
A separate 'tilt', shelve, and parametric EQ with at least 3 separate settings. a 'tube' setting which in one switch would give a 'tube sound'
All this is one box, analogue, not digital. I want one, want a person to try one out to develope it.. pick me. (if you want to make a digital one, just buy a behringer EQ2496, perk up it's analogue circuits, and put your name on it)
Bryston could be famous:" the company that brough back tone controls!!!"
3) make the BP-26 with gain adjust. My BP-26 has way too much gain. OR make a switch for the volume control to change its setting. For example my Audio Research SP-15 preamp has a front switch that cuts the vol in steps up to 24dB next to the main vol knob. This is a really useful feature. even a three position switch would do wonders for the BP-26
MY volume control on my BP-26 is useful from 8 oclock only to (at best with the phono) 2 oclock, with Cd straight in, its 8 oclock to 9 oclock max! That sucks. i use a separate tubed pre to both tube-up the Cd sound, AND cut the volume!! and yeah, i have the switch on the 4B-SST2 correnty done. (I wish I bought the pro model with the 4dB cut switch)
4) a USB gizmo. Since i know nearly NOTHING about computer audio, all I can say is it seems to be the future of audio.
