A good friend is in a conundrum - his amp is dying and he's considering new. He wants to retain his current late '80's early '90's Linn Index speakers (86dB/W) but doesn't have a huge budget, sub-£400 at best. Tone controls, a phone stage and other such fipperies are considered unnecessary. However the ability to deliver thoroughly convincing piano and naked cello is vital. Do these particular requirements skew the usual WHF recommedations or will the usual suspects deliver what's needed?
