New headphone amplifier from Bryston - Page 38

post #556 of 1470

Well, HE-6 is pretty difficult to drive... smile.gif   LCD-2/3 also need some power for the very best performance.

Why don't you PM James Tanner with your technical concerns?!

post #557 of 1470

Thanks for that. I don't have any technical concerns regarding the Brystons ability to drive high or low impedance cans. The specs speak for themselves, it should work very well for both. I do however think that the Luxman is not very well suited to high impedance phones. That is my point and that is why testing the Bryston against the Luxman using 350 ohm cans seems like a waste of time.

I am here to give an update on my BHA-1 and the HE-6...

 

I have been listening to this combo for the last few weeks using a PS Audio Perfectwave DAC II as a source using balanced inputs and can say without hesitation that the BHA-1 can adequately drive the HE-6.  I have been waiting to compare it to a speaker amplifier and got the HE adapter this week.  I did some A-B comparisions between the BHA-1 and my W4S STI-500, and can say that they both sound fantastic.  

 

If anyone is hesitating about buying this to use as a general purpose headphone amplifier that can also drive the HE-6, you should buy with confidence.

 

I have used it on HD-800, W3000ANV, and HE-6 which is a pretty broad range of driving difficulty and the BHA-1 can drive the sensitive W3000ANV with plenty of volume adjustment all the way up to the HE-6 to levels that are too loud do listen to.

 

I understand the concept of headroom and the need for plenty of power for the HE-6 and the Bryston definitely performs up to my standards.  I typically leave the volume at 2-3 O'clock and have the volume output on the PWD at about 80% so I can adjust it track to track with the remote.

 

I do think that you probably need to look at the output voltage of your source/pre-amp as I think the PWD is a bit higher than usual, and I cannot speak for running it with single-ended input.

 

Anyway, I owned the BHA-1 prior to the HE-6 and planned to use my speaker amps if the BHA-1 didn't cut it, but I have found that I actually prefer to use the BHA-1 over the speaker amp.

 

In fact, if I had had the BHA-1 first, I probably would never have bought the WA-22...

 

Let the flame war begin!

Thanx for your impressions!

 

Did you notice any distorsion driving BHA-1 with 100% volume on PWD, i.e. 5.6V?

post #560 of 1470

No distortion at all.  I just keep it lower so if I get a song that comes up that is quieter than the rest I can change it since there is no remote on the Bryston and I tend to sit away from the component rack.

That is very interesting. How does the BHA-1 compare to the WA-22 with the HE-6?

I'm planning to run a second round of comparisons using the 21-ohm UERM.

Having lived with the combo for 2 1/2 years, I can tell you that your numbers-based theory about the P-200's inability to drive the Senns does not survive contact with the real world. My experience using it with LCD-3s leads mt to believe that the published specs are very conservative.
post #563 of 1470

The LCD-3 is around 50 ohms. Fine for the P-200.

WA-22 is not powerful enough for HE-6 IMHO.  It sounds pretty good at very low levels, but I think at normal listening levels, the amp ends up cranked all the way up and just doesn't have enough juice...

 

The WA-22 has a very special synergy with the HD-800 though and in some ways is nicer than the BHA-1, but in reality they both sound great, just different.  I just think that for the asking price of the BHA-1, you get a very well rounded amp that will drive pretty much every headphone.  Other than the hobby aspect of wanting to try/compare everything, I don't see any reason to look further than this amp.

 

I may not have what it takes to be an audiophile though (I must not be critical enough of what I buy, because I like almost all of it).  Or maybe I just do really good research and get the right thing right off the bat.

 

I bought the W4S STI-500 as a "temporary" amp because I wanted to get really nice speakers.  However, I am so pleased with it, I may just keep it permanently.  I am sure that curiosity will eventually get the best of me and I will want to try either a really high end Class A, a nice tube amp, or the new Hypex N-core, but really, the W4S is an awesome amp too, just like the BHA-1.

Based on the specs, that's less than 1/2 W into the LCD-3s. Barely enough juice for orthos. While they're low impedance, orthos need moar power. 1.5W would be minimum for them IME for them to really open up.

Many thanks, Senn your impressions are much appreciated. I find it interesting that the Bryston has an easier time with the HE-6 than the WA-22 does. According to the specs the WW-22 has much more power into low impedance than the Bryston, but clearly specs are not everything. By the way, have you got any speakers yet? It would be sad to let that W4S go to waste.

I used to own both the HE-6 and WA22 and the WA22 was far from being up to the task to driving them properly. The Mjolinir looks like a better headphone amp option.

Seems like some people here disagree. Before reading some of the above posts, ostensibly made by people who have tried the equipment themselves, I was under the impression that the Bryston with 1/2 W into 32 ohms would be struggling with orthos and like you said, more power would be needed. Apparently not, according to posts above. Specs are not everything.

I think the Bryston puts more than 1/2 W into 32 ohms. (6W into 32 ohms with 1% THD).

Might explain why some like the Bryston with the LCD-3s. wink.gif

Thanks. Finally things start to make sense. I was looking at this http://bryston.com/PDF/brochures/BHA1_BROCHURE.pdf ...
