Does anyone have experience with 45 tubes?  I aks because Eddie Current is coming out with a new tube amp.  The EC 445.  It takes 4 45 tubes.  How does these tube do with the HD800s in comparison to the 2A3 tubs?

 

I use a 45-based amp for speakers.  It takes 2A3s as well but I prefer the sound of the 45 -- especially the globes.  45s are overall more magical than the 2A3s, a tad less coltish, with a more balanced, ethereal mid-range and deeper, more articulated bass.  The 45 has a unique ability to shine a light around the music.  I am very interested in this new EC amp.  Do you know if it's just 4 45s, meaning a 45 driving a 45 for each channel? That would make it the holy grail of headphone amps in my book -- all DHT all the time...

Don't really know anymore details.  The proto has not been made yet.  It may be a proto for the upcoming LA meet.  We'll have to wait and see.

More expensive conditioners will not only filter but try to adjust a stable output to hardware.

 

 

 

It depends on what conditioner you have. Do you use a surge protector at the moment?

 

I don't think so...

I'd look into it, they don't cost that much and will save your investment from any harmful surges in the power supply that can have the potential to damage your equipment.

Has anyone found a nice travel case for the HD800's?

Having just purchased a used Graham Slee SOLO headamp for another system I joined up to discuss items on their board and spotted a thread on the HD800 so put in a post:

Wow, did that stir things with Graham Lee.  If interested, please have a look at what he says about the HD800 and put some comments here on what you think about his view!  One Head-fier has commented to me he could be right.  But then again he might not be.

Seem like he not an HD800 fan. I think they sound great with both the V200 amp and also my CSP2 tube amp. I also disagree about it being a digital headphone. it plays the recording like it was recorded whether its vinyl or digital. If the recording is bad it will let you know it if it is a great recording it will reward you also.  It his forum and I guess he entitled to his opinion as well but I disagree with the digital part.

Look in my photos for the right Pelican case # which is same size as the Audeze case but tapered. 

 

I lined the inside of the case with Self-Adhesive Creatology Foam.  (It keeps the HD800 warmer and does not allow the peaks to build up while transporting them. wink_face.gif)

post #6400 of 6594

Nice! Thanks, I'm going to have to do that.

 

The HD800 world would be a brighter place without creatology foam and colorware.

post #6401 of 6594

I'm interested since I use my HD800s on a Graham Slee Solo SRG. But most of what's in that thread is way over my head. The HD800s have a "very slight 'plasticky' sound" on his amps?

 

I've been enjoying these headphones with the Solo. Maybe a year from now I'd like to buy a good tube amp, like the Woo WA2, but I'm not hearing any serious flaws right now.

Please elaborate more.

It is a little known fact that one of Sennheiser's achievements with the HD800 was to source the neodymium for the magnet from a specific rare earth mineral ore in China which includes a mix of several other elements undergoing radioactive decay. The radiactive nuclei of these elements emit electrons through beta decay at such a rate that, in Senn's magnet implementation of the magnet structure, there's a greater magnetic flux density. Now don't worry, the magnet's far enough from human tissue that there's only a negligible risk of mitochondrial DNA damage and the half-life is in the centuries, so performance should remain relatively constant throughout the HD800's lifetime use. Creatology foam and colorware's matte paint are commonly used mods to absorb some of this radiation, which is composed of both electrons and photons, hence "less bright". Sorry for the pun :)

Ah,  by less bright I guessing you mean the "bright treble"?  That's very interesting.  I ask because I'm expecting a pair from coloware next week but with the glossy paint.  

 

Um - you called this a mod, so I guess it subjectively provides a tamer treble?

post #6405 of 6594
Yup, at least that's what I heard with the matte. Interested in finding out on how the glossy sounds!
