Well this is quite a revelation for me! Since getting my amp back I am rediscovering its joys and finding new ones.
I think firstly that using the AK120 has proved to be a substantial increase in quality over my last source, the HM-801. I knew listening from the headphone out that the AK120 was the better player but only by plugging it into a high quality amp can I see how much better it is!
There is a refinement and maturity of the sound that one generally only gets in the better DAC's in home systems. Also this is as close as I have come in portable audio to albums on CD sounding like vinyl. Two played tonight show that for me. Phil Collins first solo album, Face Value and Roxy Music's Avalon.
I have owned both albums over the years on vinyl, CD and cassette. Both on CD were lacklustre, especially Avalon, sounded thin and laking dynamics. Ripped from CD to FLAC via XLD These albums on the AK120/TU-05 combination sound so different to the CD they were ripped from. I can only put that down to the player (as I tried them right out of the HP out and they sounded great) but also in combination with the 05 that great went to,"what, this cannot happen, how can this happen"?
Honestly, they both have the warmth, the feeling of intimacy (especially Face Value) that I last heard on Vinyl and Cassette. This player is outstanding and the 05 just shows that so much more. Likewise the 120 shows even more what an incredible design Shikada San has created here with this amp.
Also, I think as well it must be said that my new isolation platform is working beautifully. With it what little noise floor there is with this amp just disappears completely ( and when I say noise floor I mean the tubes not the amp which is always silent in my experience) The tubes are deadly silent and the music just hangs in an inky black deep space. Sheila Jordan's voice just hangs there. Three dimensional, breathy and intimate. I have not heard this CD rip sound better!
The last thing and I think one of the most important which really ties all these positives together is this cheap little Audioquest cable. It is truly astonishing as it simply does not impart anything in the sonic. Every time I put the Cardas in the music becomes softer and less emotional. Switch to the Kimber and the music feels rough. Go back to the Audioquest and well, its just music, nothing added, nothing taken away.
Its not a fashionable cable. It has no ultra expensive exotic materials, just solid long grain copper conductors but it does what Audioquest has as its motto, "first do no harm".
The other thing this new set up has done is show me how truly great a design the Beyerdynamic T5P's are. With great equipment they show that they simply reproduce the signal they are given. If there is deep bass its there, if not then the T5P does not make up stories. It is not like the HD800 which many say is better, I just find unemotional. I have yet to hear that headphone, even with tubes, involve me in music. Great for analyzing the last degree I agree but for me it is a studio tool not a headphone to enjoy a wide range of music with which saddens me as I love Sennheiser!
I have said this before but will say it again with some additions. The TU-05 to me is like a Nagra pre amp in they way it delivers music. Go listen to one if you get the chance, you will see what I mean! The AK120 for me is in many ways very similar to an experience I have many years ago when I got to listen to DCS's original Elgar DAC which when I heard it was used in conjunction with a Wadia transport. There was an intimacy and detail about that set up that was intoxicating and whilst I would not dream of saying the AK120 is the same it gives a very similar feeling that I felt listening to that set up in terms of musical involvement. Who would have thought a mere 13 years later that I could be saying that about a portable player!
Lastly the T5P's to me are the headphone equivalent of Wilson speakers in terms of transparency and the ability to convey musical emotion and timing. I actually said that to Debby (Dave Wilson's daughter) a little while ago and she went and listened to a a pair and understood what I meant!
So there we are. I am so glad that my amp is back, music has never sounded better!
