I'm saving up for either a Benchmark or a Transporter. In the meantime, I got a Beresford to try out. It needed modding before I was happy with it. My Perpetual Technologies P-3A is now on eBay.
Here's my experience with the Beresford for those venturing forth: - When I got it I found both the fixed and variable outputs noisy (slight hiss from the speakers when I put my ear next to them (the P-3A is almost silent) - From what I can tell from the circuit board, the variable output is driven via the headphone circuitry and it was picking up mains hum at a certain setting. For both reasons I am now using only the fixed output. - I modded the unit as follows: (i) LM4562MA op-amp to replace the NJM4558 on the fixed output. It's a £6 drop-in surface mount replacement. (ii) Changed the power supply caps to some good quality low-ESR types. (iii) Replaced the switched-mode power supply with a linear one to eliminate the switching noise that I could see on my scope. (iv) Applied Mr Beresford's Mod21 mod, as my unit is a 6/3 version and not the latest 6/4. For the price I am now very happy with the sound. Disclaimer: This is just my opinion and, no, I did not ABX the mods. I have no dealings with Beresford apart from being a customer. -- plim ------------------------------------------------------------------------ plim's Profile: http://forums.slimdevices.com/member.php?userid=7051 View this thread: http://forums.slimdevices.com/showthread.php?t=54947
