The Stax Thread III

Thank you for your suggestion, I'll be on the lookout for the SR007 for hopefully one within that price range but may I ask what makes the SRD-7 special enough it can be ran with the SR007, is it because it relies on an amplifier to power it, has a lot of mods to increase performance or is it really just a great deal for the price? I'm sorry, still trying to learn everything.

It's more than enough. I'm paring it with 100W Class D Speaker Amp.

I got the SR007 for about 110,000 Yen and SRD-7 (Pro Mod) for about 25,000 Yen

That is the big advantage of the SRD-7 Pro, is that just about any power amp will work with it. I use either a Golden Tube SE40 or a Cary Rocket 88 to power my headphones. Both are tube amps and to an extent I can roll tubes to the sound I like.

+1 The exact reason I am drawn to energizers over dedicated amps for electrostatic head phones myself.

Thank you all for explaining how diverse and adjustable the SRD-7 is with it costing much less. I will for sure check the links, you sent and watch the whole video. @zomkung I do have a question that'll help me a lot, by the sounds of it, you did purchase your equipment from Japan Auctions but I have no clue how much the shipping will cost which is why I've been hesitant, I would greatly appreciate it if you don't mind telling me the rough estimate it was, thank you. I didn't know a used pair of SR007 was within that price range and they look soooo comfortable with those earpads. I actually have been ignoring them due to the price tag but I will look much more into them since from what I did glance over, they're amazing. I do have a 6W, 50W, and 300W from the 90s but it's extremely warm but dirty sounding, I thought it sounded warmer than my friends schiit Valhalla but it is physically impossible currently to have no volume even at 0.

Thank you all again for your comments and that does make it much easier to afford amplifiers and an energizer for stax giving more diversity and unique experiences.

Please correct me if I am wrong about anything since unknowledgeable.

It's close to impossible to find SRD7 mkII pro for 200$ nowadays and on top of that you need a 500$+ amplifier to power your headphones through a SRD7 box. Do not underestimate SR207's or old SR404/407's with SRM252S amp. Good budget combo. 404LE + SRM252S should sound fine too. SRM323(or later models) is also a great amp, any combo including that amp and a decent lambda is worth to consider buying.

I won this auction with 28,500 YEN (Including SR-5 MOD)
https://page.auctions.yahoo.co.jp/jp/auction/l681676453

Also for the Speaker amplifier, I'm pairing it with a 30$ 100 W Chinese Class D Speaker Amp and have enough power more than it needs.

For the shipping cost, you may check the price here https://buyee.jp/help/yahoo/guide/shipping-fees , Mine was around 10,000 YEN with an Airmail(5 KG).

Driving SR007 off a 30$ class D amp doesn't sound like the best idea to me honestly but if you like what you hear, that's great. Not only the amp but the transformer used inside the energizer makes difference in sound quality too.

I have bought a used SR-009 but alas it came from a smoker. I have replaced the earpads already, but the headpad still smells a bit despite using leather cleaner.

I am wondering if anyone knows how I can get a replacement head pad? I have a friend in Japan if there are any Japanese source for spare parts?

Thank you!

I paid $300 for my SRD-7 Pro a while back. I see them on eBay maybe twice a year and often for a lot more money. I can here differences with different amps, so the transformer has advantages in that manner plus buying speaker amps is usually less expensive than buying electrostatic headphone amps. I have a set of SR404 headphones and I enjoy them very much. You may want to also consider a new pair of Nectar Pollinators or Hives, they are inexpensive and give you an outstanding introduction to electrostatic headphones. If you like an IEM earphone set up consider the SR003 or the portable SR002 with battery powered amp. I have a pair of the SR002 and amp and they sound great.

Power adapter for SRM-252S:

https://www.jameco.com/webapp/wcs/stores/servlet/Product_10001_10001_203036_-1

It has 1.5A compare to the stock 0.5A power adapter. Will it be any better is sound?
I already bought it but not sure if I can hear the difference on my L300. I've only had it for a few weeks.
Higher amperage won't have any effect - SRM252S won't draw more than it has to.
Only a linear power supply can improve SQ, and even then it will be difficult to tell the difference - at least you'll be able to relax and think that you have done all you could :jecklinsmile:

I'm using a linear power supply I purchased on Aliexpress - https://www.aliexpress.com/item/1000004386010.html .
You can either ask the seller to reverse the polarity, or buy a cable that reverses polarity.
