Da ex possessore di Beyerdynamic DT880 250Ohm e DT990 600Ohm posso dire che le Beyer necessitano, per esprimersi al meglio, di amplificazioni "muscolose", in grado di erogare corrente con cuffie ad alta impedenza. Non conosco per esperienza diretta il Beyerdynamic A20, ma credo che sia stato progettato per dare il massimo con cuffie dello stesso marchio. Io posso consigliarti ilDocet 10, un ampli sul mercato da tempo ma ancora decisamente valido, con le DT880 e DT990 anche timbricamente ci andava a nozze. In più risparmieresti pure un centone rispetto all'A20, il che non sarebbe male.

Direi che in quel caso il Creative sarebbe l'anello debole della catena.”
Io ho letto tante cose buone dell'A20 in accoppiata con le DT 770 Pro 80Ohm e le 1990 Pro 250Ohm
Te ne copio e incollo due sulle 770
1)Warren's Beyerdynamic DT 770 Pro 80-Ohm: Since the A 20 is a Beyer amp, I instinctively wanted to reach for some Beyer headphones. Unfortunately, both my DT 1350 and my DT 880 headphones were away on long-term loans. That left me with a humble pair of DT 770 Pro (80-Ohm) closed-back headphones.
I didn't know it at the time, but this turned out to be very serendipitous pairing.
Taking a jaunt through Taylor Eigsti's "Get Your Hopes Up" from his Lucky to Be Me album, I was rewarded with a very nicely weighted low-frequency response that remained unusually clean and tight from the sub-bass through the mid-bass and into the lower mids. Both the double bass and Taylor's lower-octave piano work came alive with excellent separation and texture. I've always been rather annoyed by bass bleed, or thick and indistinct lower mids, so I was delighted to find almost none of that here.
The entire mid-range presentation of the A 20 and DT 770 pairing was exceptionally clean - cleaner, more detailed, and better separated than I've ever heard from a DT 770. There was no hint of stridency or congestion all the way through the upper mids and into the highs. And the highs came through with both richness and shimmer surrounded by a wonderful and airy openness - which surprised me considering the DT 770 is a closed-back headphone. The staging and imaging characteristics were also very good, almost on-par with the best I've heard from a pair of closed-backs.
In hindsight, the pairing of the A 20 and the DT 770 sounded the most "correct" out of all the pairings I've tried. It sounded "right" - to the point where I enjoyed the music viscerally and without cerebral interference.
If - by some strange chance - you're looking at the A 20 with the intention of driving a Beyerdynamic DT 770, you can stop reading this review right now, and simply buy the A 20. Your search is over, mission accomplished.
2)TESTING WITH THE BEYERDYNAMIC A 20 AMP
Reviewing the DT 770 PRO 80 Ohm I thought it would be appropriate to use the Beyerdynamic A 20 amplifier. I also used a few highly regarded albums to reference via the in-house Fiio X5 (3rd generation). The source files were FLAC in order to get the best possible sound. I figured this would be a great way to see just how “reference worthy” the DT 770 PRO really is.

I spent about 30-40 minutes listening to some of my favorite tracks from 3 albums… The Eagles “Hotel California”, Michael Jackson “Thriller” and Tears For Fears “Songs From The Big Chair”. After reminiscing about good times I found myself quite impressed with the overall frequency response. The DT 770 PRO 80 Ohm headphone brought the best out of each mix with the reference quality of even more expensive headphones. I found the bass to be perfectly punchy and every element in each track was crystal clear. It was a truly flat sound through the vocals in the mid-range and up into the very high frequencies most people don’t even know exist in the music they listen to. The top end was brilliant and brought out the true emotion of the musicians and vocalists. I even found myself reliving the good old days of watching MTV with hits like Michael Jacksons “Beat It” and “Thriller. Listening to “Head Over Heels” by Tears For Fears reminded me of the genius filmography of the movie “Donnie Darko” which used the song in the soundtrack. “Hotel California” never sounded so clear.
The bottom line is the Beyerdynamic DT 770 PRO 80 Ohm passed the reference test. The only thing I found to be an issue was the upper mids and high frequencies were bright with a few tracks. Especially on some of the Michael Jackson tracks but in all honesty my “everyday headphones” don’t have such a high frequency range so it’s just something I’m not used to.
Testing the Beyerdynamic DT 770 PRO 80 Ohm closed-back headphone was the best part of my week. I got the chance to reminisce some great times via the classic tracks that accompanied them. Better yet I discovered a really cool headphone for under $200 that’s excellent for studio mixing, mastering, audiophile listening and even broadcast applications. .
This headphone may not be quite in the same class as the DT 1770 and DT 1990, however the Beyerdynamic DT 770 PRO 80 Ohm is an excellent headphone for the price. The DT 770 PRO 80 Ohm headphone is truly a reference class headphone that will give you the advantage for your home studio but is still suited well for Studio A at a top-notch recording facility. You should definitely check it out.
Riguardo la X - FI HD secondo te quanto ci perderei?
In caso poi si potrebbe comunque cambiare, stavo guardando il Musical Fidelity V90-DAC(aspetto il parere di un utente di un'altro forum che l'ha comprato da poco) o comunque, se c'è qualcosa su quella fascia ascolto anche consigli.
