Another impression!
Ive been listening the V281 amp via single-ended mode, my Balanced cable will arrive soon and the amp works beautiful with all of my headphones, but, the big surprise is the K701!
Yes! LCD-2 sound awesome out of it, also the Denon AH-D7000, but thats something I expected, what I did not expect at all was the big improvement in the AKG K701s.
The AKG K701 is a headphones that either you love it or hate it, I was in the "love it" side, but there was something I didnt like about the K701, the mid-treble transition. The K701s have a strange, harshy peak around 5-6khz that harsh a little bit, more if the recording isnt a quality one. Also, the bass department, unless you use tubes, always has been a bit thin, I liked it in this way tho, for classical music and OSTs, but for other styles it laked punch and body.
Well, I decided that the time had come to test the K701 with my new amp, and WOW, the K701 just evolved into a new level!!
That harsh area near the treble almost dissapeared, and this is not burn-in related at all, the headphones has up to 2000 hours of use and I know it very very well. But the treble just calmed down a bit in that side, having all the extension the K701 always had, just add the plus of smoothness and a controlled situation and you got it!! Awesome.
Also the mids part has been increased in resolution, clarity and a bit of body, which makes the headphones more fun to listen with rock/blues styles.
The bass department boosted up, the sub-bass area goes very deep and this is easily noticeable, electronic music and the punch of drums sound much better. Also the overall bass has a tighter and punchier feeling, giving drums and percusion instruments more presence.
As I say, this was a total surprise. I tried the K701s with many headphone and integrated amps, and Ive never heard it like this. Not even from tubes (marantz and McIntosh amps). Tubes gave it a smoother sound, but just smoother at all, a bit bassier, but the bass wasnt controlled at all, it was muddy, but the V281 gives very well controlled tight bass while smoothing the treble and increasing transparency and body of mids, and all this with the typical Violectric black background.
Also the soundstage imaging got to another level, now sounds more realism.
