The Headcase Stax thread

Someone last year in this thread got a new 007a with a 2300 serial so getting 2406 today suggests current production to me.

    Arrived yesterday and it really opens up every electrostatic headphone that I own. I was looking for an amp that can bring more bass out of my HE90 than HEV90 so I drained my pocket to bid on this and

  • I have been getting back at this..working up to a limited run of these as the STAX SR-X9000 and Audeze CRBN have made that need to happen. But the chassis is extraordinarily expensive and difficult to

Welp happy to say I think I'll be joining the Stax gang finally!

I wound up picking up one of the CCS Modded SRM 007tA's from @spritzer I'm sure it'll be lovely for my ESP 95X but I'm curious if any one has any experience with the CCS Modded Tube amps for 009? Ideally I'd like a bright/lean Stax to compliment my some what dark 95X

I'm not an expert but aren't Stax plug already balanced?

Stupid: Yeah but I got a 3D printer.

All Stax are balanced and even if an amp has two outputs... they are wired in parallel with both channels at both sockets.  What benefit could be had from this is very dubious. 

Maybe the guy though it would be a headphone equivalent of loudspeaker bi-wiring?

Shotgun cables is the term used I believe?

Save your money,  you don't need the 007 because your 009BK is the best.😛

Just because a manufacturer labels something a flagship does not make it better than a previous flagship. But you wouldn’t know that since you are simply a troll.

There's a thread over at HF for you to share this knowledge.

@Lord_Rexter

As much as I love the SR-009BK, most of the time I reach for the SR-007 Mk1 more. They're more genre friendly.

In a perfect world I'd want both, but seeing as I have a Koss 95X I don't really need something tuned like 007, I'm likely going to pick up a 009 my self to compliment my 95X.

Now when the time comes, yes I'm 100% going to add a 007 MK 1 to my collection as I think both 009 and 007 can/are complimentary 

@Katusha Did you read your welcome message? If not, I would strongly suggest finding it.

I think there are a few more in this thread lately that should shut up, or reading their welcome message or getting the shovel. Please, Nate.

Agreed, And if "flagship" product refers to the most expensive model in the line, my experience is that it does not guarantee that the more expensive model necessarily outperforms the less expensive ones.

I have both the 007 and 009 on hand, I like them both. Each has its merits and faults. In addition to the music genre, I pick which one to listen with based on my mood-swing and sometimes the alignment of the moon and sun.

I've got Koss 950, so unless the Koss 95X sounds totally different from the 950. Which I doubt, I don't see how 007 Koss 95X tuned alike.

I can see something coming for a couple of accounts being the same user.

I agree. I do think the Koss 95X/950 can sound good, especially if you liberate them from the pedestrian energizer they come with and use whichever better amp you use to play your STAX, but they aren't really similar to the 007.

Good feed back thank you! An yea I've got a nice CCS Modded SRM007tA that should be liberation enough

Imo 007 when I've heard it had been very "thick" real mid focused presentation and not quite energetic enough up top for my tastes, 95X is imo slightly thick, relative to an HD 800, and not quite energetic enough up top at all times 

Still to be frank the idea is to get a hold of 009 and work my way thru reviewing literally everything else I can get, so I can have my own opinion of them all. But I've heard 009 dozens of time and it's always been MORE than energetic to my ears and never came off as quite like 95X does and 007 when I've heard it in the past

Now let me ask this, how do you guys who own them presently feel 007 MK 2.9 differs from 95X and 009?

Ahh my ebay feed is such a rich source of crap.  Now this:

Pics here for when the listing goes down.  Standard KGSSHV but with a few twists:

Notice that their are no terminal blocks which is bad but one bonus, this amp will kill your headphones.  Can anybody spot it?  It's not the twisted output leads which are a terrible idea... 

 

 

The bias is tied to the "bias tp" which is just for measuring the bias... before the ballast resistor!!  So yeah, no ballast so say goodby to your diaphragms. 

Spritzer, these posts make me feel like I should only ever buy amps from you or Justin.

Edit: forgot to include ecp audio!

There is nothing wrong with DIY and we try to make the PCB's as simple as they can be but it is a whole other matter to sell that DIY design after butchering the basics...
