Have been somewhat experimenting with some combo's the last 2 weeks.
Tried Tera with RS Shadow and afterwards the RS mini interlink as well, both nice upgrades.
Together with the Grado GR10 makes a nice combo and for me personally even better with the Shure SE846.
The latter combo provides a kind of movie theatre sound with a really great sub bass section.
Then realised again that the Tera is built en tuned for a higher impedance headphone instead of IEM's.
Started to listen more to the Tera - Koss combo and actually enjoyed it better and better.
The Koss doesn't fit me too well though, my ears start to hurt and I wanted a bit more resolution.
So decided to buy the Senn HD 25 SP II.
I know, by figures not the best HD 25 but pricewise nice, very lightweight, simple, not much clamping force,
hardly any enviroment noise, sturdy, no need to be carefull with it and above all 60 Ohm! (think Koss :-))
Let it play for about 6 hours but wasn't too heavily impressed:
- Soundstage was mwah
- Too much undefined bass
- Slightly sibilant
- Bit veiled presentation over the entire spectrum
So searching this great forum found some possible mods to be done, with many thanks to jfunk!
Did surgery upon the HD, removed the white back felt ring in the cups behind the driver, put sticky damping
material in the cups and closed 2 small holes in the frame of the driver as shown in the other thread.
Result was some clarity gained but not enough improvement to my tase in the bass section.
Opened the cups again, removed the damping over the 2 holes in the frame of the driver and
closed 2 other ventilation sections (should anybody be interested, I'll post some pictures).
Closed the contraption again, connected to the Tera, started listening and almost fainted......
Impressions after about one hour of listening:
- Wider soundstage
- Improved 3D stage
- Bass (for me) exactly the right amount and nicely controlled
- Mids foreward, great vocals
- Treble no hint of sibilance anymore but silky smooth
- All frequenties rather equally presented, none of them overpowering the others
- Effortless relaxed playback (I love that)
- Fast and punchy when the musics needs it
- Musical instead of analytical, it grabs me emotionally
- This combo clearly has more "the analogue Tera sound" without the extra amping
- Hardly any problems with more complex music
- Very open sound sig, moving in the direction of Grado's house sound but warmer.
And... playing directly from the Tera, no amping, no double chargers, small sturdy package, etc.
Maybe I will decide this is as good as it gets, I'm satisfied, no more experimenting.
Just maybe.... :-)
Meanwhile for sale:
- Shure SE846, Grado GR10, RS the Shadow, RS mini cable, AKG 701, NAD HP50, Musical Fidelity EB50,
Hifiman 602, Fiio X5, the rest
Mind you, all of the above is of course subjective, comes from to my personal hearing and
little knowledge and needs to be placed within the limits of a €150 headphone.
But very well worth trying and enjoying for those who like using the Koss.
