In my experience there are actually 3 "generations" of the M50. M50 (approx. 2007 to approx. 2010): Bassy and V-shaped. Very good. M50 (approx. 2010 and forwards): Less bassy and V-shaped. Also very good M50X: Even less bass and very different sound signature. I don't like it. IMO: try to to...

BTW, The Niimbus US4 has +/- 30 V like the older Violectrics. Quote from the manual: "Two toroidal transformers each with 25 Watt are providing the internal operating voltages of +/-30 V."

OK, the manual confirms it has + / - 25 V internal operating voltage, so less than original series Violectrics that have + / - 30 V.

Side-note: After checking the manuals of different Violectric manuals, it seems that my HPA V90-model (discontinued) gives the most voltage to 600 ohm cans (unbalanced)in the Violectric series: 600 ohm load: V90: dBU 28,6 / V 20,9 / 730 mW V200: dBU 27,6 / V18,5 / 570 mW DHA V590 lists 21...

On CMAs official site for this amp ( https://www.cma.audio/en/detail/index/sArticle/2057 ) it says: "High Output Voltage - through 50 V internal operating voltage." Does this mean +/- 50 V or +/- 25 V ? The previous Violectric series has +/- 30 V (60 V).

Thanks! Anyone else?

Can you name some powerful all-tube amps that can rival Violectric-amps in output/voltage swing? Also: what is the most powerful all-tube amp for headphones available, if price isn't an issue?

After reading about the silent revision of the M50 I bought a New Old Stock original ATH-M50 in the blue/white box with flip-cover, and I can confirm that there are 3 different versions of M50/M50x: v1: 2007-2011/12 (?): blue/white box with flip-cover: Significantly more bass than v2, otherwise...

Has anyone tried this amp? Couldn't find any reviews/info when I searched. (The company's website is in german only, so use Chrome's Translate function) http://www.xn--ptter-jua.de/Produkte/MAX44/max44.html

I love my M50s, but need something smaller with better sound isolation. Can you recommend som IEMs similar to them in sound signature. Budget: 200 USD. Minimal sound leakage is a must!   PS: I did search, but all suitable recommendations are over 5 years old.

I love my M50s, but need something smaller with better sound isolation. Can you recommend som IEMs in the price range 50-250 USD with punch(!), heavy bass and polite treble similar to the M50 sound signature?   PS: minimal sound leakage is a must!

Couldn't find a thread about these. Seems like a gimmick to me, but maybe useful for some people, if they sound good.   https://www.kickstarter.com/projects/inspero/vinci-first-smart-3d-headphones-that-understand-yo

What is the internal voltage swing of the 339 at the power stage? (an example: My Violectric amp has +/- 30 V)  

Can you recommend some warm-sounding, cheap studio monitor speakers? Not too large, $200-$400 per speaker?   To be used for music listening, not mixing/mastering.   I prefer a somewhat V-shaped sound signature

Hi   Can you guys recommend some good medium sized speakers with on/off/volume-knob on the front? Currently I have a pair of Creative Inspire T10. I checked out the Audioengine A5+, but they're a bit big, and also it doesn't seem possible to turn them off using the front volume knob.  ...

Thanks for the replies, everybody! Ordered the Yamaha MT-220s (got a good price).

I've read that the M70 is very much _not_ like the M50s (too analytical etc.), but I am of course curious about them. The TH600 are too pricey for me.   Can you recommend 2 closed and 2 open headphones that have a V-shaped signature like the M50s in the price range $200-400?

I really love the sound of the M50s, but are there other headphones that sound similar, BUT BETTER!? :-) Also more comfortable? I also really like the Sennheiser HD-25s. These are my two favourite headphones by far.

I really love the ATH-M50s soundwise, but I'm also looking for an upgrade that sounds like them/better, but are more comfortable. Do the Meze 99s really _sound_ like the M50s? Can they handle loud sound pressures?   Any others to recommend?   (For reference, I also love my HD25s, and use a...

I'm going to Hamburg and I want to try the Sennheiser HD 800 (S) with a proper amp. Can someone recommend a store in Hamburg that has it?

According to Sennheiser they are still made in Ireland.

I've noticed the HD 25 has got new printing on it, and "MADE IN IRELAND" on top of the headband has been removed. Can someone confirm that the new ones still are made in Ireland (it should say on the box).

bump

Does anyone know this? Almost all (all?) other cans I've seen with a single-sided cable has it on the _left_ side. (I've personally changed this manually on my HD25)

Listening on my new 7520s through my Violectric V90, and all I can say is: YESSSS! :-D   Such punch and clarity! I bought these since I really like the 7506 and boy are they an upgrade.    My number 3 favourite is the Sennheiser HD 25 (yes, I prefer closed studio monitor cans), so all I can...
