Well, buying used is always an option, but you then run the risk of parts may need replacing, depending on age use, etc.. A new amp should give you more peace of mind. What does the BHSE offer over the KGST? I have listened to a couple of headphones on a BHSE, and I can say it is a great amp. I have also listened to the Carbon CC, which is an outstanding amp as well. I have yet to listen to any of the KG series and would love to compare them to some of the others I have listened to.

Hey Spritzer, would static- guard anti static spray work?

Hey Spritzer, what are you using to coat the X1’s diaphragm?

PS try eBay and see what prices you can on that.

Same place mine broke. I also tried to repair them with h a plastic welder, but alas to no avail. So I ordered a new L700 mk2 arc and it arrived the other day. Much better fit and is a more robust design.

Any news on the imbalance of the X1 Stax?

Where are you located?

Don’t forget the early Koss estats! The ESP 6, 7, 8, 9, and the 10. I have the ESP 6, ESP 9b, and the ESP 10, all sealed. I am sure this new one will seriously out perform all my Koss headphones.

Or it could be that they are using sources such as DAPs or USB stick amp/ DACs, they can use a bit of a boost.

I would love for you to do a write up the D amps. I use one of 3 amps with mine. The Golden Tube SE40, the Aragon 8008, and a Carry Rocket 88 are my usual suspects for amplifying headphones. I do have a few other amps that I could use but they need repair.

I am glad you told me that, I would not want to buy bogus transistors. So with that in n mind, I will continue to use my SRD-7 Pro and my SRM 212, and save up for a better amp.

So if I use them as. A sub. Is this a plug and play transistor or do I need to mod something.

Thanks Spritzer. I know I asked you if there were subs for those transistors.

I was looking for 2SB832 four of them

Yes the older Stax amps do offer a way into the Stax world. But be weary that many have parts that are no longer available. I have a Buyer beware on older Stax amps. Many have parts that are no longer available. I have a SRM 1/ MK2 that I tried to refurbish but some of the transistors are not to be found at any price. I know the Stax SRM1 is loaded with obsolete discontinued parts. If you were to look at this point of view, Topping at least has modern and available parts. Design wise the topping is iffy at best. Maybe Birger and Mr Gilmore can give us a list of Stax amps that have replacement parts issues so others can make better informed decisions.

Look up online the owners manuals of Koss ESP7,8,9 and they have a oscope printout of a 400 hz square wave. It looks as bad as the Topping. These models of the ESP all use an external transformer box (the ESP6 had its transformers in headset, heavy and uncomfortable) hfe_koss_esp-7_en 2.pdf

Based on measurements only, and Topping products usually measure very well.

Interesting write up Spritzer. When you have time, tell us what changes Topping should make.

The old SRD-x Pro was a transformer driven by an amp. That may be a he best comparison for this amp.

Get a Stax SR003 and the cs1 kit. Isolates very well If you are taking it somewhere there is the SR002 iem portable. I have the SR002 and an adapter so I can use it with a SRM 212. The little battery operated amp is actually pretty good.

Has any one seen a Stax SRM-1/MK2 like this before?

Hi Our Man in Paris Thanks for that info, and that is a very good analogy of cameras.

Just dropped to best price yet, $249.99. Well worth that price

Has anyone used the Sigma headphones for listening to pop/rock or blues? If so how do they handle that type of music?

Any one have any experience with ES Labs Sigma headphones?
