Dear all, as promised, here you have a brief comparison between:
1.The Beresford TC-7520 DAC with original op-amps and the linear PSU using the built-in headphone output.
2.The Meier Stagedac coupled with the GS Solo and linear PSU (connected through Crystal Cable Piccolo).
Let me start saying that this is not a fair contest. It is like comparing an Volkswagen golf 1.6l with an Audi A3 3.2l: they are both good cars but do not cost the same nor deliver the same thrill (I have driven both, by the way so I know how it feels). In a nutshell, the Beresford is like a nice family car: takes you where you want to go with no problems but not much fun. The combo Stagedac/Graham Slee is like the A3 3.2l: it makes you smile all the way through the journey and you can push it to fly (and leave behind the irritating white vans).
Down to business: both were connected through optical Fisual cable to my Sony SACD. For the comparison I used the HD650 with Silver Dragon cable for the listening. I also used the Grados GS1000i which only accentuated the differences I heard with the HD650. The Stagedac had the crossfeed disconnected and it was in position 3:1 (top filter with x8 oversampling).
First tune was Rodrigo y Gabriela version of Metallicas' Orion from their 2006 album. This is an audiophile grade CD, with both guitars very well recorded and with very natural acoustics. The Beresford sounded very good and smooth, but a lot of detail was missing. The woodiness of the guitars and the decay of the notes wasn't quite right. Don't get me wrong, it was a very nice sound, but it sounded as you expect a good CD to sound rather than how you expect two guitars to sound. I connected the Stagedac/GS and played the same track. Well, totally different experience altogether: the separation between the guitars was better, the sparkle in the strings was there and I had more detail I could possibly care for. It was incredibly clean, fast and accurate. No possible comparison here, the combo was playing in the Premier the Leage and the Beresford just in the First. I din't consider to compare in more depth because the difference was so big that it made no point. I listened also to some songs from Buena Vista Social Club “At Carnegie Hall” and the same effect: clarity, detail, pace, tone, everything was in a different level of quality, almost real (the Buena Vista Social Club band came to tour Scotland as part of their UK tour three weeks ago and I was fortunate enough to go to their concert in Aberdeen. What an experience! Even without Ibrahin Ferrer, Compay Segundo and Eliades Ochoa this group just put an smile in your face. If they go near your city, do not miss it).
I know this review is not as detailed as my previous ones but, honestly, it's like comparing ugly Betty with Scarlett Johansson, you do not know where to start because you cannot take your eyes off Scarlett. Saying that, the Bereford is a great DAC/Headamp for the price and it is giving me hours of pleasure when I'm with my PC. No complaints at all, it is just not good enough for serious listening sessions. By the way, I tried also the USB input on both and the differences where also clear there. One thing worth noting is that the Beresford do not seem to suffer from jitter through the USB (nor does the Stagedac) and that is a hell of a feat for the price.
That is my opinion for what is worth.
Yours
