Can AHB2 + SRD7 drive 007 and 009 properly? I was thinking about AHB2 for Susvara and was wondering if SRD7 (or similar) would be a good combo? Or I still need KGSS?

It certainly has the power to do it, it all comes down to how it sounds to you.
Would be worth at try if all you need to buy is the SRD7.

I just want to buy one universal amp, and AHB2 has power for Susvara. I don't want to spend another $3k for a Stax amp.

You can get an SRD7 for $250, or maybe a little more if you’re looking for one that also works with Pro bias. My normal bias SRD7SB is in the classifieds and I use another with both Pro and Normal outputs - one of those might be for sale too. If you have a serviceable speaker amp, I think an SRD7 is a perfect little add on.

Edit: the seller I bought mine from has one going for $180 right now, pro and normal.

Could you please share the link?

I am using this LPS with upgraded Talema transformer: https://www.aliexpress.com/item/DC5...-noise-DC-linear-regulated/1000004386010.html
Asked the seller to reverse polarity and add a second cable.
Can't say I hear any changes in SQ using 253S, but it just feels right to use LPS.

Thank you.

Of the NB Stax I've tried, the Lambda NB probably is the "best" one but I ended up being very partial to the SR-X Mk3 and I still have an SRM-1/Mk2 on hand basically just to run the Mk3 if I'm ever so inclined.

I also love the way the Mk3 looks but that has nothing to do with the sound lol.

I think the next step for my setup might be the energizer route with an iFi iESL, largely because I still want the normal bias compatibility.

Thanks, just ordered a pair of NB’s...

Have owned pro’s in the past that I thought were very good.

Will advise when received and how they compare to my 404 I have on hand.

My review of the 007 MK1. Hope it helps?

My review of the 007 MK1. Hope it helps?

great review, thank you.

SR-007 MKI is my favorite electrostatic headphone (and despite some similarities, I find it hard to believe that the MKII is only a revision). Unlike the SR-009, the SR-007 MKI can sing, it is a headphone, so to speak, that has a great musical talent, i.e. it is a great interpreter, a hermeneutical talent that its younger and technically superior brother does not possess.

My review of the 007 MK1. Hope it helps?

Good review. Definitely agree on the impressions. Also I was really taken back by just how authoritative the bass is recently. Overall, just a really phone pair of headphones.

Hi @Sajid Amit ,

Great review!
I was wondering if you found the SR-007 bass better than the Susvaras?
Overall, how does the SR-007 compare to the SR-009s you've recently reviewed?

Have anybody tried new electrostatic energizer from Bottlehead?

Hey Axel, off the Carbon, the bass is definitely stronger than the Susvara’s, although the Susvara bass is absolutely fine with a copper cable off my Hegel H95.
The SR007 MK1 is more musical than the 009S; more meat on the bones; richer tone; warmer/darker; etc.
I personally prefer the MK1 to the 009S, although the 009S is more technically proficient.
To me, the 007 does just fine as per technical parameters and the best part is, it works across all genres and tracks.
The bass actually thumps with the right chain behind it.
All Stax hps are source picky.
Funny thing: the 007 sounds better to my ears off an Aries II DAC than the Holo May, the amplifier being the same, i.e., the KGSSHV Carbon.

Yes, I have the blue one in that link. I like it a lot, it pairs well with my NBs. It’s powerful enough for all my Lambdas but the es1a come across a little rolled off - still very musical and detailed but not as sparkly as my CCS 006t. I would guess it’s not great for the 007.

I have a Bottlehead Crack too, and it brings some of that flavor to estats. It has a CCS, so it’s like a Speedballed Crack.

It’s actually interesting to know how much does the SR-007mk2 differ from the mk1.

I have the mk2 and I found your review pretty much similar to what I’m experiencing.
Except now that I have the LCD-4z driven by the Viva Egoista 845, the bass is a class or two above that of the SR-007mk2.
Although the SR-007mk2 mids are truly amazing.
Other aspects, like sounstage depth are also surpassed by the LCD-4z.
In general the SR-007mk2 have a very big sound but rather flat in depth. The highs are very easy on the ear.

I'm only referring to 007mkII mk2.9 here.(has different response than mk 2.5)

MKII's are slightly more detailed than MKI but also darker.
MKII's are a bit more airy.
MKII's are shouty in 1000-1300hz range, mids are colored compared to MKI.(spring mod solves this problem a bit)

MKII needs blu tac mod to have tight, deep sub bass extension.
