Around $2200......, maybe 2500 if you wait it out and its in good shape. which it probably is.

Ok, sounds good. I paid $2400 back in '07. Brand new.

The 7B vs a 14B: 7B each amp next to speaker, SHORT speaker cords. Many find that to be a BIG positive factor for monoblocks. I mean if you have expensive speaker cables.. WOW. the cost difference could pay for some equipment!

You are right about the positive benefits but my speakers are only 150 watt with 6in main drivers. The small benefits didn't justify the big aggravation i would have wanted to do.

I considered the 7B's but there are hidden costs associated with the 7B. Obviously power cords for me... you need two. Also i would  have only done the 7B's if could get them right behind each speaker. That would have required a reinventing of my wiring and outlets feeding each 7B. And then you have to cable it. Here xlr's would be needed for longer length runs... needed those. I also would want to shorten my speaker cable. Since i loved the speaker cable i used i would never have found it used at the shorter lengths i wanted, and i hate cutting up good cable to make shorter lengths that are manufacture terminated.


The 14B fit right into my system with no real changes.

No that just isn't so, you need longer xlr's and if they are the same make as speaker cable, one higher cost just gets transfered to another lower cost. It evens out.
Thanks - Good information.

James,

Do you have a curve or at least a few data points that relate the BP26's SNR to volume settings...both (and/or) o'clock position and db attenuation/boost?

Hi KnowTalent,

Here are the noise measurements for you -less than 2dB between 9, 12, and 3 oclock positions on the volume control on the BP26 preamp.

Those are excellent specs :thumb:   I would seriously doubt anyone would hear a audible difference based upon volume setting.  Thanks for the education and legwork required to provide this information...not many others would comply with such a radical request.  :icon_lol:

I  agree...Bryston does go the distance for people.You have to be grateful for that.

Agree, very impressive, both the graph of the volume control, AND the willingness to publish it here.
Thanks!

Details like that make me feel proud of my purchases, I'm glad the James and the group at Bryston are able to do this.   I just wish other manufactures would as well, or at least sets a higher bar for them.

I can only imagine what it would be like for the consumer if all companies provided the same high level of customer service such as Bryston.

Be well…

Stereophile's review of the Ayre KXR preamp was partially responsible for me following this line of questioning with Bryston.
From the "measurements" section of the review they compare the new KXR VGT volume control to that of their "lower" priced K-5xe which measures ~95 db SNR at max volume and 75 db SNR with 20 db volume attenuation.

Since Bryston's measurements at various volumes are essentially flat regarding SNR I now must drawn the conclusion that Stereophiles comments regarding the "uniqueness" of the VGT circuit are "hype" when regarding its ability to deliver a flat SNR vs. volumes settings....save maybe for when compared against other "lower" priced products in Ayres line up.

The BP26 is roughly the same cost as the K-5xe and yet delivers performance on par with the $18,500 KXR :thumb:

That's why I read and ask questions

While I agree that typical measurements can not totally characterise a components "sound" it is still a rather moronic comment imo as there are many who don't have local dealers, stocking $18K preamps  :roll:... and therefore no way to convienently demo equipment...therefore specs are often a way to weed out BS designs from the real performers.  If a manufacturer refuses to list specs they either are incapable or they're hiding something imo...both situations give me pause. 

It's like people who buy amps guided mainly by watts rating...without knowing current output capabilities and other little "specs" that have no direct correlation to "sound"  :lol:

Peak current and raw weight of an amplifier are "usually" important indicators as to what power an amp is truely capable of regardless of "sound".  If you don't have the power to generate the spls you desire I can tell you a underpowered/overworked amp is going to sound like dookey :thumb: ...regardless of any marketing drool-excuses put forth by the infidels
