Bryston's BP-26 vs 17 cubed


I’m curious if anyone has done a serious comparison of Bryston’s BP-26 and the 17 cubed? I have been demoing the 17 cubed for approx. 40 hours now. Previous preamp was Classe’ Sigma SSP. My other gear consists of Joseph Audio Pearl 20/20, Classe’ CAM-600, PS Audio Memory player and Directstream Senior. I like the 17 and will be demoing the 26 towards the end of the month. The 17 has a nice warmth to it without sounding too syrupy. From what I have gathered the 26 will have more punch towards the base mid-range, and perhaps more detail? I have narrowed it down to either of these two units, not interested in other preamp suggestions. If anyone can shed some insight into this it will be greatly appreciated.

Thank You Soix. Your input is very helpful. I can't get my hands (or ears in this case) on a 26 until the end of Jan. It will be very interesting to compare these units. I have a very revealing system, as mentioned my current gear, dedicated circuits, Furutech Power Cables, Cardas Clear Reflection speaker cables. I might overlook the lack of warmth aspect if the detail is such as you explained. Detail is not such a bad thing! As you well know until you hear the piece in your own system one never really knows. Its interesting the Canada folks use the 26 in the audio shows, the American sales guy uses the 17? Thanks Again! If you think of anything else please let me know...
I had a BP -25 for 5 years until I upgraded 18 months ago to a BP-17. Less noise (shrillness) and surprisingly better bass. 
Thanks man, I'm still going to demo the 26 and compare it to the 17 cubed. From the input I have received it sounds as though the 17 is more refined. However until I hear it within my system I really won't be able to know. Kind of a cool experiment! Thanks...John
The salesman from Audioadvisor said he would get the BP-17. I got mine closer to home
I spoke with AudioAdviser, not many dealers have the 26 in stock, they have to be made. I'm liking what I hear with this 17 I'm demoing. Just want to make sure, hence, this is why I'm demoing a 26 at the end of the month. Everyone who I have spoke with who knows the 26 say very upfront, and detailed. My system is extremely revealing, so it will be fun to hear both pieces of gear. What speakers are you using? Also what is your power source with the 17? Thanks for your input...John
