1) The BP17 and BP26 use the same circuit but the components differ between through hole parts (BP26) and Surface mount parts (BP17).

2) The MM input impedance is 47k ohms.

3) The BP26 MC input impedance is 180 ohms - we can provide 25 ohms and 5 ohms as well.

4) The BP17 is currently MM only.



Hope this helps

James, I had a follow up question (now that I got the BP17-3 with MM phono) about the TF-2. Why is the input impedance fixed at 47k per the user manual? Normally step up transformers just echo the MM stage's impedance by a factor of the turns ratio, unless they are configurable with additional resistors, which gives the user some flexibility in cartridge loading.

Note: I sent an email to Stuart a few days ago, asking to confirm if the manual is correct.

HI

The 47k is the standard input loading of the MM preamp. There is no input resistor to the MC transformer. I can email you the MC transformer JT-44K-DX data sheet for clarification if you need it.

Good, that's what I was hoping. Thanks for the Jensen part number. Their data sheet for the 1:10 transformer indicates Zi = 470 ohm which makes sense.

Order placed for TF2-20

SUBJECT: Bryston Phono Stage – New Review – Coming Soon

August 2018

Hi Folks,

A superb in-depth review on the Bryston Phono stage is due out shortly in a new NOVO Magazine ‘High-End’ online publication – will send complete review link when available.

Sneak peek below.



The Bryston BP-2 MM/MC Phono Preamp/With The PS-3 Power Supply:

By Andre Marc

“In fact, the Bryston BP-2 MM/MC phono stage revealed so much of what was in the grooves it provided an incentive to engage in record hunting, which this household has not done for a while since we own a healthy collection.


Out came the wallet and during this review, we scored several choice pressings that have been on the shopping list.

Having had hundreds of review components come through our system, it has never been so difficult facing the notion packing up and sending back gear to the manufacturer.

This Bryston phono stage pair was simply transformative for my vinyl listening.”

SUBJECT: Golden Ear Award – Bryston BLP-1 Turntable

August 2018

Hi Folks,

Bryston is very pleased to announce that the Bryston BLP-1 Turntable has received a Golden Ear Award in the 2018 issue of the Absolute Sound magazine.

Bryston Turntable and Tonearm

Supplied with record weight, dust cover (three cheers!), and the company's proprietary BTP-1 outboard pulse-with-modulation power supply, this belt- driven two-speed turntable boasts exceptional speed accuracy and spot- on rendition of pitch, timing, rhythm, and togetherness.

Bass is deep and powerful with remarkable resistance to external disturbances despite its fixed plinth (though it's quite the best compact, lightweight turntable I've ever used).

All up and down the scale the BLP-1 provides a neutral platform of great composure grip, and dynamic range with commendable quiet backgrounds. The tube of the nine-inch gimbal-bearing tonearm is constructed in seven segments of differing diameters the better to deal with unwanted resonances. (Bryston challenges the need for anti-skating but will provide it if requested)

Offering joy of vinyl at a level of performance that gets you to the threshold of the so-called "super" turntables without the fussiness, the need for continual adjustment, and the sheer anxiety that all too often accompanies some esoteric setups.

Bryston just couldn't have made life in the vinyl lane easier or more inviting than with the BLP-1.

It's a rather old thread, but I wanted to add that I have not been enough fortunate to own Bryston equipment other than my 2 step-up transformers. One of them being their first one which had been made by Cotter for Bryston. It sounds amazing. Later I managed to get their TF-1 which supposed to be an upgrade over the Cotter version.
Indeed it sounds different, but if it is better or not, it's hard to tell. In my setup the Cotter sounds nicer to my ears.
