Arcam Black Box 50 dac - 100% refurbished and upgraded

Every electrolytic cap has been replaced with an upgrade - Nichicon, Elna and Panasonic.

Output caps were Rubycon electrolytic bi-polar types but now the dac sports Vishay film capacitors in this crucial position.

Main power supply cap also bypassed with a Vishay film cap.

Power supply input cable now Neotech. Fuse is an AMR.

Lots of chassis dampening.

Opamps on the dac board were NE5532 but now universal gold plated dip sockets have been added to allow for opamp rolling. Opamps in the dac are now 2604 upgrades - big improvement.

Some chips coated with Audio Magic Blackout Paint.

Grounding post added so the likes of an Entreq can be attached - works well.

41 component upgrades in total - like a new dac for old money.

Very quiet background to this dac. Very detailed and ‘quick’ sounding. Lots of ‘air’ and insight to the music. Big upgrade over a stock unit. Negative is it is not that emotionally engaging - it does not do it all.

No original box or manual but will be well packed.

£180 incl UK post.

Worth mentioning the built in clock link to get rid of jitter. I had a BB 250 that had one and very useful it was too with the matching transport. I read somewhere that a new generation of transport were compatible with the clock link in these Arcam BBs, and had given them a new lease of life, but I can't remember the details.

Edit: can't find the details about a new transport but I looked it up and it is Deltran which I know DPA used and also Colin at Chevron Audio.
