MEMO: To All Bryston Customers SUBJECT: BHA – 1 Headphone Amp Review January 2016 HI Folks Please see link below – review on the Bryston BHA-1 Headphone Amplifier from Secrets of Home Theater and High Fidelity Magazine...

Hi   Yes the outputs are in parallel so both should work at the same time.   james

Hi   Yes the XLR part of the cable has to be wired a specific way.   Email Mike at Bryston and he can send you a drawing or you can order the cable from us.   mpickett@bryston.com   james

Hi   Yes you can use them to drive powered speakers.   james

Hi, I have had my BHA-1 for a few years now and just wanted to drop you a line to let you know how much I enjoy it. For my loudspeaker system, I have a 300B SET amp driving full-range drivers, so I am familiar with the liquid sound of a good tube amp. I mention this because I always find...

 Hi   No problem at all.   james

Hi Whisky   The red light does mean overheating - do you have it well ventilated?  The BHA1 is a pure Class A amplifier and the top acts as a heatsink.   james

Email Mike Pickett at Bryston and he can describe what needs to be done.  Then you can decide the best option.   mpickett@bryston.com   james

    OK - you can order a faceplate through the distributor.   james

    Hi    Yes as stated above volume controls will have a little imbalance at very low levels - usually once you get above 8 o'clock things will be very accurate from that point on.  We laser trim our controls within a 1/4dB from 8 up.   You can have a rack-mount installed - where are you...

Hi James   The balanced input buffer runs out of headroom with 7 volts input.

  Hi   That is strange - let me ask engineering for you.   james

Hi   Sent you an email   james

Hi Folks,   I prefer the balanced out but a lot will depend on the efficiency of your phones.   james

Oh I see what you mean - no the outboard power supply does not necessarily mean better performance assuming you design and do proper shielding with an internal supply.   Our original idea was to allow the DAC and the CD Player we had at the time to also plug into the MPS-2 but we found it...

HI   The BP26 MUST be used with the MPS-2 as there is no internal power supply.   james

HI    The outboard power supply option has been discontinued.  We found it did not make any difference in performance.   james

Hi Folks   Serial numbers after 50 will have the preamp outputs.   james

Hi   No plans at the moment and it would have to be a different product.   james

  Hi    Yes the first 49 did not have the Balanced outs since then all of the BHA-1's have the preouts   james

Hi, Have just purchased a 'new to me' BHA-1 unit to go with my Sennheisser HD800s. Prior set up was all HiFiMan rig, including their excellent EF5 Hybrid Tube amp. All I can say is what a revelation. While my HD800s certainly sounded wonderful with the HiFiMan EF5, they simply sing and...

Hi Folks,   I wrote this a while ago but it may help.   Is Your System Out Of Balance?   One question which keeps coming up over and over is the controversy regarding audio components being "fully balanced" versus what is sometimes referred to as "balanced converting to single ended" at...

Hi James, I thought I'd take the time to tell you I received my BHA-1 and am blown away. The build quality is truly excellent, switches and volume pot feel fantastic. Turns out the balanced question was semi irrelevant because this thing has made my HD800 scale up hugely, plugged in single...

 My apology - From Engineering:     Yes he is correct. The rear output has 50 ohms isolation resistors in series with the signal  and is not expected to drive headphones only line inputs 10k ohms or above. This is easily modified if necessary. NOTE: The an overall load impedance on theBHA1...
