I definitely need to try BHA-1 since even BP26 is step ahead from Gustard H10 working with low impedance cans

Well, I think it's a great choice for your HE-560's if you go the balanced route. If you are looking at buying one with the TH900 in mind you may want to order it with the low-gain reduction mod in place depending on your preferred genres. But I would expect a brighter sound, especially if you find the H10 bright (try switching op-amps in that one - a good thread on that). Otherwise you may just have to EQ a bit to your liking.

First time i hear on low-gain reduction mode,. Is it some specific model? Some prefix?

Mine was a used model and I'd be happy to look up the code numbers for you tonight if you like. I think most that had it done were retrofits (mine included). Are your concerns with too much gain for the low-impedance TH900's? All it will do is reduce the overall gain when in the low-gain switch position. That would give you more usable range on the low-gain switch if it is too high for your headphones. It won't change the frequency response or overall sound, simply reduce the gain and give you more range if the amp is too powerful for your needs.

I can assure you that the BHA-1 / TH-900 combo works very well in low gain.

 

Excellent in fact.

No, not a specific model. A dealer can arrange to have it sent to Bryston, or better, have a tech do the adjustment in-store. It involves switching some resistors inside the existing unit. I had mine adjusted in-store, to allow me to use the fuller volume range -- it was too loud for me at just 10 o'clock, on L gain. Now, I can use it at a comfy volume at around 1-130 o'clock, and ear-damaging levels at 4 o'clock.

Somewhere in this thread James had elaborated on the order codes they use that spell out the options.

 

Gibalok - you can PM James Tanner here - he's the top dog at Bryston. That's his username here too. Might be the easiest way to find out how to get one in Moscow if you're buying it new.

Thank you. I know some local dealers where i bought pre and amp. It seams that bryston again will prove it proficiency for me smily_headphones1.gif

As far as I am aware it was earlier produced units that the option was given to get the low gain output dropped down a few notches.

 

The more recently built units however have this "stepped down" feature already included. 

 

Idea being that Bryston was able to find a happy place in "low gain land" that would accommodate lower Imp headphones better.

 

(Low gain land is a fictitious place....do not attempt to book a flight)

Well its hard to arguing when my knowledge of technical nuances are limited (high/low gain design and volume control w/o loss of details). From my big system i know that BP26 gives me more dinamics and resolution on low volumes comparing to even good digital volume control used in modern DACs (Mcintosh D100, Wadia 121/122) directly to power amp (4bsst2) but again im not sure whether its connected to BHA-1 "low gain land" advancements and its synergy with low impedance cans.

Interesting observations / findings.
