Any of you know the brand or have experience with any of their amps?
Does 2000Euro sound fair for such a amp (a few years old)? A new amp from Mjölnir cost 5100USD + shipping and taxes.
There is a builder in Denmark, he will make one for you properly...
Well worth the extra cost, you rarely see amps like these on the used market (and they get sold pretty quickly).

New to the forum but have been following your STAX talks for quite some time.
I have found a offer for a used KGSSHV Carbon that I have been looking for to pair with my STAX SR-009 (or a Blue Hawaii).
It is build by Felitsa Audio and as far as I can find online it is a guy from Vietnam selling his amps via ebay.
But I cant any review of their amps or owner experience.

He builds quite competent amps. As for pricing, no idea

Don't mix things up, from the pictures it looks like the one that used for the comparison wasn't built by him.
As for the other amp, seems to be the case of you get what you pay for...
To be fair the build referenced was a DIY build, not the commercial product AFAIK.

That's good to hear, although I guess the parts or the design haven't changed all that much.
So it is still the case of having way less parts and way less power compared to a (properly-built) Carbon, which I really don't see a lot of people complaining about.
As for the builder of that other amp, he is still flagged for incomplete sales.
So if he has improved in the meantime, why doesn't he take the necessary steps to resolve that?

I'm talking about this one: https://www.head-case.org/forums/topic/786-the-headcase-stax-thread/?do=findComment&comment=835661

That's the DIY kit version of a 500 EUR MSRP amp not a carbon.

As for that one: https://www.open-end-music.com/foru...ize/9959-neuer-stax-thread/page291#post614386
I don't know who might have built it

Thanks guys for the input.
My end goal is definitely to get a Blue Hawaii or some of the higher end amps from a good builder.
But after just having spend a significant sum on my DAC I cant afford one of those at the moment.
I can afford the Felitsa Audio KGSSHV Carbon now and I am thinking it should be a good upgrade from the SRM-007tII that will make my SR-009 sound nicer while I wait.

Google is your friend. You may want to do some research - particularly on headcase where there have been some recent postings about this.

I did a stupid, sold my 4040 system and now I have...nothing but an SRD7SB. Sigh.

Anyone from western EU have a decently priced (~€2k) Stax rig for sale? Can be a 007Mk2.9 for example.

We are using convolution filters designed for other headphones with the SR-007. We understand these filters equalize to a target curve, and will not make headphone "A" sound like headphone "B"

In the case of the SR-009 filter, there is a bump below 150 Hz that--in my opinion--works well with the SR-007.
Where can I find the convolution filter for the SR-009?

Works very well for my 007 + 009 and very easy using the ROON DSP CONVOLVER!
