New headphone amplifier from Bryston - Page 87

post #1291 of 2090

I have owned plenty headphone amplifiers and still do in fact. Most of them were custom designs but to this day I have not found a more neutral amplifier than the BHA-1. I purchased it very early and so the serial number is very low as well but when I initially said it was the best match for the HD800, people laughed at me. I still maintain it is siginificantly better than Sennheiser's own amplifiers when HD800 are in question. The neutrality is inevitably the reason why it sounds good with various headphones. Bryston's philosophy was always that of neutrality in terms of response but more importantly, in terms of colour of the tone. By providing clean amplification with nothing added or taken away, it allows for other components in the system to contribute their character. Having high quality electronics does pay off here because if your source is of the same breed (not necessarily the same make make), you will hear nothing but the recording and for me, that is as good as it gets in high fidelity.

 

I have read somewhere on this thread that a new headphone from AKG is coming. It is something I have been waiting for years, much like a Pass labs headphone amplifier. It looks like we could see both next year! Given Pass' affection for "you-are-there" kind of an approach with slightly more presence than with Bryston amplifiers, I think it would be equally good, if not better, in some respects. But Bryston has it's own merits and so I am I am very pleased with how people have finally started to realize why it might be a highly desirable amplifier.

 

Cheers!

I agree totally. BHA-1 is the KING of headamps, for me. A chameleon.

Which actually says a lot for a piece of Bryston gear 20 years old as their approach has always been to produce gear that as neutral as possible, mind you although the sonic signature is the same there is some residual noise with the .4 if the volume on the .4 and 2BLP pro are maxed to 100%, 50% or less would be used for loud monitoring with inefficient phones which makes any noises completely inaudible at listening levels but which still can effect the final amplified signal which could be perceived as less air.

But Bryston have not sitting been idle and have continued over the years at reducing any unwanted electronic residual which would effect the purity of the input signal.

The current BHA-1, AFAICT, has eliminated any source of noise, producing an extremely black back-round letting the tiniest detail emerge; one can be assured the BHA-1 is as good as they come.

 

But the whole point the exercise though was to show that if one has an old Bryston .4 or.5/ 2BLP pro combo sitting idle IMHO they make a very good headphone amp but the BHA-1 is the new champ:beyersmile: 

 

That's impressive. Longevity has always been one of Bryston's claims, and I believe it now. I think plugging in the BHA-1 and everything else (sources, etc.) into a very good power conditioner will lower the noise floor even more :o2smile:

 

Now, back to bed...unfinished pleasure there....:tongue_smile:

Took the words out of my mouth.

As they say, Bryston's Philosophy is to make equipment as neutral as possible so do not expect their equipment to impress if your looking to enhance some missing element to the recording, if it's not there the BHA-1 not going to add it. Which is the charm of using headphones, none are perfect and like speakers are the weakest link in the chain (barring a bad recording) but the cost of having a few a few phones on hand is relatively inexpensive (compared to high end speakers) and  allows one to choose the pair to fit the mood.;)

I like this type of thinking guys!

 

I'm thinking about selling a few headphone amps and only using a BHA-1.

I tried the headphone jack in my Bryston 2B-LP and found myself underwhelmed! frown.gif

 

BTW, I'm a big fan of Threshold and Bryston gear.

 

 

Hi Chris

 

The BHA-1 and the Bryston .4pre/2BLP pro combo share a lot of similarities, what did you use as a pre on the 2BLP or did you go direct and balanced or use an adapter "RCA to balanced" ( do not use a RCA to 1/4" as it stresses the amp:confused_face_2:), I'm using a properly wired RCA to XLR and it makes a huge difference. ;)

 

 

 

The noise floor of the BHA-1 appears non-existent, but as you mentioned in another thread there is some hiss with the 2BLP (it is a power amp not to forget), with most of my phones it's not an issue though and with so much reserve on hand IMHO it's great for inefficient phones, aka "K501s":smile: .

Oi, mate! 

I use the Bryston 2B-LP with a Bryston SP-1.7 pre-amp.

So I am using the balanced outputs on the SP-1.7 to drive the balanced inputs on my 2B-LP.

I found the hiss to be slightly objectionable when I used AKG Q701s plugged into the 2B-LP's headphone jack.  

 

Obviously the cable shown in your photo is used to allow an SE output pre-amp to drive a power amp which has a balanced input.

I agree about properly wired adaptor cable, I used to use one of those cables when I had a vacuum tube pre-amp with SE outputs into a power amp with balanced inputs. :beerchug:

 

BTW,

It would not matter whether the power amp had an XLR or TRS 1/4" phone jack input. 

 

I've also tried driving 2,000 Ohm headphones straight from a power amp..............seriously! :eek:

I've never heard those headphones sound better!

Looks like you got the bases covered, so maybe a BHA-1 (darkest back round I've yet to experience) is in the stars!

Hi There

 

The connectors must be "balanced" on "both ends" to have a balanced circuit.

We know that James, as for me I'm just tinkering around.:smile:

Hi Chris

 

I'm speaking of one of these.


Not too sure how many times I've seen these attached to the back of a 2BLP-pro balanced input to accommodate an unbalanced preamp (older 2BLP-pros only had a 1/4 balanced input, more current ones provide a dual input 1/4/ XLR socket) , the amp may sound fine but will get very hot in no time at all, even with headphones.

For those who wish to run two unbalanced sources to the BHA-1 this cable config works fine for the balanced in, in fact you can have three obviously if one also employs the mini jack input.

 

But as James said.
