  I think faster transients get misinterpreted for brightness.

I know what you mean (I think), but I would put it differently:
 
Faster transients should mean a less bright sound. I.e. that the transient is handled exactly right, without overshoot, overhang or ringing. When a component appears to put emphasis on transients, i.e. appears brighter, it is probably due to some combination of overshoot, overhang or ringing.
 
I have no idea where the 009 fits into this, but I don't think the BHSE has a problem in this area - at least not with the right tubes

The HE60 is one of the fastest headphones around, and friends who have had the brightness issue with the SR009 have not reported the same issue with my HE60.

My BHSE #47 Have return to Justin for repair for almost 4 Months already. When can it be back?

I will be out of town on Oct for months. and this is the 2nd time my BHSE fail on same problem. Is there any better way to settle the Problem?

 

[justin w.]

i am still working on it and will definitely get it back to you before october. there is a lot of corrosion on the RCA jacks so i am looking at many things as potential problems. is the amp exposed to salt water?

 

[arnaud]

Months away from home, corrosion on the plugs, angry to not get the amp back just before leaving, humm... Can I guess this BHSE is crossing the oceans the slow way?

#47s re-sale value plummets.

 

[t1174]

Of cos no water on it. salt or un salt.

I am even run it near by my bed and have air cond on.

but it is true that Hong Kong have a wet weather, but not in my bed room. And bhse is the only amp I have fail in this 2 years.

 

[spritzer]

Corrosion on those jacks... how is that even possible?

Oops!

Maybe the #47 really need a details test. Also it is really out off time. Shippment to HongKong already need a week.

May Justin keep the amp and ship it on late Nov? I back to Hong Kong on Nov.

 

[t1174]

I think may be cause by bullet plug.

the rca cable I use is a bullet plug silver and that is really tie.

This looks like a question you should ask Justin, don't you think?

gold plating probably got scratched off

For anyone who's got a fully discrete balanced DAC that includes both XLR and RCA. Have you tried connecting both at the same time to BHSE, and use the toggle switch (input) to compare the sound on the fly? I'm leaning towards RCA...

 

[padam]

The gain will be different, so difficult to make an objective comparison.
But the less signal conversions = better.
So, if you have a true balanced source (and/or use longer cables) use XLR, otherwise use RCA, simple as that.
