🔶 Fostex T50rp

Martward · July 29, 2020, 9:14pm

Do you think my E10k would do the job? I’m really at a loss for what headphones to pick for $200 or less and the used market over here is pretty much non-existant. Also there are close to no shops where I can try headphones so I’m pretty much bound to buy blindly.

Go with ZMF’s I had the proteins on my t60, and now the suedes, sooo nice.

LeDechaine · July 29, 2020, 9:59pm

Fiio E10K is apparently 200mw at 32ohms… nope. I would not risk it.

Still for 100$ you can get one watt or more power, from a JDS Labs Atom amp (not recommended: too much treble for T50RPs), or Schiit Heresy, or Liquid Spark (Laid-back treble apparently, so, great pairing), etc.

Edit: Also Fiio K5 Pro for 150$ for a dac AND amp. Topping L30 for 130$, with a pre-out switch for speakers.

Hmm, not sure I can set aside that much at the moment, especially since all the $99 amps are not available where I live (at least not for $99).
I guess it’s back to the drawing board .

Yup, just make a new thread asking for easy-to-drive headphones (with a Fiio E10K) as an upgrade to your MH752s. I’m thinking AKG K371s maybe, otherwise, I don’t know.

Does anyone know of a good balanced mod service for T50RP? I know Modhouse has one on their website, but claim that they aren’t doing it for existing headphones. (I have Dekoni Blues, but from my understanding, they are just Dekoni’s variant of a T50RP Mk3)

will my Fiio BTR5k be enough for these? Zeos mentions that it pushes the T60RP’s “it’s like a quarter of a watt and it shouldn’t push those but it does”. But in his review, he said that these are the most inefficient headphones ever (at least in 2016).

Yes, it will make sound on a btr5, but it’s not sound you will want to listen to for very long. The key thing in Z’s video is the T60’s are modded to run balanced. You only get “1/4 watt” balanced. So if your mkiii’s are modded balanced, then you’re good to go. If not, my experience is it sounds bad single ended.

Alright, thanks.

LeDechaine · September 11, 2020, 2:14am

I can confirm 250mW of Class A power is enough for T50RPs, but with calm songs the volume pot will be at max. I’m currently listening to a rock album with my T50RPs and my SMSL sAp-1 (90$ Class A amp, 270mW). Volume at 75%.

500mW is the minimum, imo. Just to be certain. It just would be stupid to buy an amp and a calm song you like isn’t loud enough for you because they did not use compression in the studio. I’d get a xduoo xd-05 (non-plus, or the brand new “basic” with integrated bluetooth if you prefer, both have 500mW – no need for the 1 watt “plus” I think).

(…I almost screwed up and wrote “250 watts of Class A is enough”, lol. “Oof!”)

Would not have been INcorrect. That would be plenty of power. If you bridged that Mono, Zeos might even agree it’s enough power.

MazeFrame · September 11, 2020, 10:51am

That sounds like a youtube video…
“I ran 500W into my headphones, here is what happend”

Do this headphone go on sale often? I want to grab a pair to mod🤙

Syxb98 · March 12, 2021, 7:54pm

I’m very interested in getting a pair of the T50rps to trial, but am worried that my current setup won’t power these properly.

Does anyone have experience powering the T50s off the ifi zen dac? (running of USB power only)

LeDechaine · March 12, 2021, 8:35pm

6.3mm S-BAL (SE) 230mW@32 Ohm… I’d be surprised.
My 270mW amp can run my Fostex T50RPs… but it’s Class A (smsl sap-1).

Otherwise I always said you need one watt for these (95% of the time they’re plugged into my JDS Atom amp, which is 1 watt, at high gain, volume at 10 o’clock ).

LeDechaine · March 12, 2021, 8:37pm

…Zeos said he could finally hear bass with the T50RPs?

Thiuda · March 14, 2021, 12:45pm

Hi, did you test the AKG K-270/ K-271 Foam Net Pieces?
I am curious if they fit the T50 and how they change the sound.

LeDechaine · March 14, 2021, 2:45pm

Oh well, sorry, I completely forgot about these foam pieces (I wanted to order something from Thomann, but did not).

But @MazeFrame did it, see pics here.

Also, welcome to the forum!

Thiuda · March 14, 2021, 3:27pm

Thank you for the link with pictures, i searched myself but could not find pictures.
They could be a little bigger i guess.

Found two different ones for AKG, a larger version for K240:

And a Version with a center cutout for K701:

There also is a Version for HD650 (DMS was mentioning it):
