Won't that affect fidelity?

Ooops!

Post edited to read 6 Watts per channel.


As for the whole balanced to single ended to balanced thing, a lot of people have a lot of opinions.

Personally I will say that a properly designed ( i.e. tightly matched) balanced input rejects noise, it does not matter if it is converted into single ended after the input stage in an enclosure that size.

Ok. I'll be testing it against the Schiit Mjolnir which is fully balanced throughout and similar power ratings so we'll see which wins. The Mjolnir is almost half the price at $750, but won't be available til July.

Mjolnir?   Huh?   I'd like to hear you say that!  k701smile.gif

I've never heard a Schiit, but I get the impression their amps are rather coloured?  Which is OK, just asking your opinion.

 

BTW,  here is a link to the Preliminary Owner's Manual:

They have no problem driving the HE-6 as I found out at CanFest in Charlotte this wknd. Great great amp....

Interesting...quite the versatile amp then. How was it with say the AT-W3000ANV, D7000s or other sensitive, highly efficient/low impedance cans?

 

Thanks Drew.

Also interested in high efficiency low impedance since I'll be using it with IEMs.
post #98 of 1502

Have not tried those. I listened to it with T1, LCD-3 and HE6 so far. The T1 was wonderful with it. So much attack. All 3 of those were good. I have to send this unit back to Bryston, but should have mine soon and can report back.

I can try my JH and UE once I have my unit in hand. Just remind me.

Thanks Drew...so far it's looking like quite a versatile amp from a great (Canadian) audio company.

Drew, the Bryston rep on another forum apparently isn't interested in answering my question regarding output impedance. Any chance you can find the output impedance on the unbalanced and balanced outputs? He said it was 'very low, but I would have to check with engineering' that was a few days ago. I'm this close to ordering, just need that last bit of info. Thanks.

Going by the Preliminary Owners Manual posted on Audio Advisor's web site, the output impedance is approx. 10 ohms, balanced or single ended.

In addition, the output is capacitor coupled, balanced or single ended.

I don't work for Bryston, maybe they can clarify or have revised the first production run since the preliminary was published.

That's not too bad, but still a bit high. Thanks.

Just an FYI. Did a little listening to the BHA-1 with HifiMan HE-6. Using the RCA inputs the volume control was at about 3 o'clock at comfortable listening volume depending on track volume from my server. With Balanced inputs about 1 to 1:30 position on the volume control. Both with gain switch in max position. With the RSA DarkStar the volume control was at about 11:30. A couple of pics for you:
