All balanced.

The Meze Empy will use a 4 pin XLR on the BHA-1

I never heard back concerning the abyss 1266 tcs. I ordered a second bha1 through simcoe audio a couple weeks back so I'm hoping they will be sufficient. The bha1 sounds great with my clears, empys, lcd 4, hd600s, sony z1r, and lcd xc btw. James, could you tell me if the bha1 has enough juice for the 1266s please.

@dmdm  While my BHA-1 is getting the mods done at the Bryston factory. I was wondering how to set this unit up. Do you have it plugged in directly to a wall socket or some power conditioner?

I have it plugged into a Richard Gray 600s power conditioner with the bda3.

So no one seems to reply to this dead thread, but I'll give it a shot. I have 2 bha1 amps. One I received today and one from 2017. The first has a lot lower gain than the new one. The volume is pretty much static from 10 to 2 and I need to crank it to 3 o'clock on low gain for similar volume on the new one at its 10 o'clock on low gain. Also, the new one's volume is progressively louder throughout the dial.   The older one is driven by a benchmark dac3b and the new one a bda3.  The benchmark jumpers are at 0 gain. Any thoughts?

The volume control on my unit also is stuck at a very low position since it gets way too loud as I turn it up. I am around 10 O'clock position, not happy about that, but not a deal breaker.

Byrston BHA-1 Serial # 1334

I used XLR cable and I am testing this out at the moment with a Benchmark DAC3B.

I am actually doing a shootout with the Benchmark HPA4.

No you misunderstand,  I like the volume of the new one. How do I get the older one louder like the new one?

I guess I just have to have the volume at 90 percent on the older one and I'm assuming this wont hurt the amp.

Question for James, can a black faceplate be purchased to replace the silver ?? if so whom do I call and how much is it and should I send it in for replacement ?  the model was manufacturer in 2015.

Lately the volume knob sometimes is noisy as there is crackling from the speakers or headphones connected to it.
Is there anything I can do myself to try and resolve this without having to send it in?
Also if I turn the volume knob up and down a few times it eventually stops being noisy, but then if I don't use it for a couple of days or so, it does it again.

Thanks,

Hi Samjay!

You might try removing the pot from the shaft (there is only one screw that holds it in place) and use a very small amount of WD-40 or some specialized agent for electrical contact rejuvenation. I found this to be the case with my BHA-1 which is a very early S/N unit. Lots of things can contribute to this and in my case, it is extremely high humditiy where I live. 97% relative humidity at +40C can't be a good thing for anyone or anything, can it?

Most conventional volume potentiometers are like this and they require frequent use and in some cases, periodic maintenance.

Cheers,
Antun
