Any tips?  

 

I think it's source-related mainly. I've found power conditioning to provide little to no gains for an unreasonably high cost if your local area is new and power is clean to begin with. It's a different matter if you live in an old building or are running multiple appliances or major electronics in the same room.

 

Source and amp is where I'd focus my energy. If you can hear cable differences, then your hearing's not the issue. If you're using a computer, the transport (USB to SPDIF converter) is just as important as the DAC, unless you buy one of the more expensive USB DACs which have decent built-in conversion. For the amp, that really depends on your preferences. But, if I were you, I'd find myself an M^3 or GS-1/Dynalo if you want high-end value. With a larger budget, you could choose from a number of amps that would sound good with the 800s.

I live in a fairly old building with un-grounded outlets and I recently got the two in this room grounded so that the M1 would stop "humming". But strangely, the humming is now inaudible with the HD 800 but still audible with my Momentums. (When you put your hand on the amp, the noise stops). I also have quite a few components sharing outlets; the amp, the dac, the iMac, a hard-drive, a router and modem and a few lamps. These are connected using standard extension outlets. 

My DAC is a USB variant, so the conversion is internal. The DAC was built for me by a friend who is very experienced in both audio and electronics and own about a dozen STAX headphones, so I take it this guy knows his deal.

You will have to invest in a power conditioning component to completely eliminate the mains hum, it will also greatly enhance the performance of your hardware.

But I've heard this can vary a lot, sometimes a power conditioner improves the sound and sometimes makes it worse?

I'd focus on the DAC and transport from what you've described. Digital tech is moving ahead at a furious pace. Next would be the amp, and then power issues.

 

From what you've posted, I don't think it warrants any power conditioning. Just sounds like some ground loop issues. That money would give you greater gains being invested in a source/amp.

I have to disagree, if the power supply quality is bad and it fluctuates then the performance of the hardware will be sub par. This is from personal experience in many locations that I lived in, including studios, etc. A 100$ surge preventer/power conditioner will in most cases solve any hum issues and filter out hums. 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?

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.

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?

post #6402 of 6600

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:

 

http://audio-forum.gspaudio.co.uk/sennheiser-hd800_topic913_page10.html

 

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)
