Caution. The 52/ Scap is a superb pre amp. Had one and sold many years ago. Regretted and got another later newer one. 10+ years ago now. If you need a pre amp then replacing a 52 will be costly. Been thinking this recently. Replace my 52 with a band new one box unit. Chord and Hegel both at the £6k mark look interesting but I suspect I'd not notice a great difference really ? Have yet to investigate.
If your 52/sc has been left powered for many years then a service may be in order. All this aside I'm currently using a Chord TT2 ( previously Cds3) into the 52. Just brilliant. I've yet to do tt2 direct into any power amp but I do need an analogue input for a home cinema pre out.
