Headamp Blue Hawaii Special Edition - Page 384

post #5746 of 6053

I can see how you came to your conclusions eric65, because David has indeed stated many times that the PH tubes have tamed his 009's brightness (compared to stock JJs and also SEDs).

But the reason is because the PHs are considerably more transparent than the JJs. They simply let the music shine through more, whereas the JJs slightly corrupt the music by smearing the images and adding a layer of grain to the upper mids and treble, which is more fatiguing - there isn't necessarily any more treble to the JJs, it's just more obvious because it isn't as refined.

 

It's the fundamental nature of the improvement that means that David can be delighted that the PHs have smoothed his 009s, whilst at the same time I can be equally delighted that the PHs have livened up my 007s. If it was just a tonal colouration, one of us would have to be disappointed.

 

I should add that all these differences are probably objectively tiny. No tube change will suddenly turn Diana Krall into Ella Fitzgerald. So people may not even notice there's a problem until they come across something better. But I'm highly sensitive to grainy/etchy/sheeny upper mids and lower treble, and tiny differences in this area can matter a lot to me.

Thank you for these details and clarification  :)

When I first got my BHSE and started listening to my 009's, I was obviously using the stock Mullard's that came with the BHSE .
At first I was very happy with what I heard, it was only when I started listening to some of the songs I have by Peter Gabriel i.e. sledge hammer and big time.
After hearing those songs which the SQ I found was very uncomfortable I decided to get a quad of SED's and they gave me the same problem.
Then after reading comments about the Psvane EL34PH tubes made by Richard and Golfnutz I eventually got a quad of those, ( I say eventually because at first there was an issue with their reliability ) and it's one of the best things I've done in audio.
I've found the highs have been tamed but to my hearing I'm getting as much detail and transparency if not more.

Now some if not most that see this post might think I'm writing a load of B--- S---, that's up to them, but every time I listen to my 009 / BHSE without forgetting the K-01, I'm a very happy head-fier.

As far as I understand, stock tubes on BHSE are not the most high-end tubes you can find, but Justin did choose them over "better" tubes (in terms of SQ) because of some potential reliability problems / availability of the most high-end ones.

On the other hand, BHSE topology is known to be not that sensible to tube rolling (I didn't write there's no effect ! :p )

Has anyone been able to try out the Sennheiser HD800s coupled with the Blue Hawaii, and what are your impressions from the synergy between both? It's not something everyone can easily try out, especially if not from the USA, so I'd love some feedback.

 

This is horrifying. The HD800 has a high sensitivity. What the HELL is wrong with this place where people are lead to believe they need much more than a basic amplifier to operate it.

 

Stick to portapros if you can't be bothered with the very basics of the hobby.

The BHSE is an electrostatic amp. with at least 1500 Volts of output.

If you don't understand what this means, then its probably not a good

idea to try and hook up an hd800 with its 300 ohm impedance.

 

Unless you want to spend about $1k or more on a pair of suitable

lundhall transformers plus another $1k for fancy silver foil capacitors.

(I will probably build one anyway just for fun)

(or find 2 pairs of esl63 transformers)

 

he60's  (not to be confused with he6) and he90's are both wonderful.

I kept the HE60/90 plug on my BHSE order - just in case I run across an HE60/90, or on the off chance that Sennheiser ever does come out with the rumored new e-stat.  Not that I am holding my breath, but I don't think I will ever run 2 headphone from the BHSE, so keeping options open.  I seem to remember he is not going to offer that any more, so I'm glad mine will be able to handle either headphone.

 

If I did have an HE60/90, I would have gone for the Aristaeus for sure, its the most awesome looking amp out there, and designed just for those Senn headphones. (NOT THE HD800 btw)

FYI, the HE90 is differ from the HE60 jack.  HE60 jack is not an option in any BHSE.  To use the HE60 with the BHSE, you will need to reterminate the cable with the Stax jack.

or some of the he60 female jacks that eric343 had made a while ago
with my new stax male plugs

Always more to learn, thanks to you both!

You should really hear a T-2. ;)

The T2 is a DIY amp, unless MacedonianHero's referring to the Stax SRM-T2 which is very rare.
post #5760 of 6053

Very rare and most of the time with reliability issues because of its extreme heat.
