CAT Legend Pre amplifier
CAT SL 1 Legend pre-amplifier – Black Path
The SL1 Legend takes an uncompromising approach further to the product with which Ken Stevens literally started the company, the SL1 preamp. (Now in its Renaissance version). The two use essentially the same circuit, but in the case of the Legend that circuit is taken to the extreme — it’s a cost-no-object implementation. On the outside, the two look nearly identical, but there are a couple of notable differences. Chief among these is the use of dual volume controls in the Legend instead of separate volume and balance.
Both preamps use stepped volume controls, essentially a set of resistors for each setting, but the Legend’s 46-position shunt volume controls are more costly than those used for the standard SL1, whose fewer positions cause issues for some owners, as the perfect volume setting can sometimes lie between two “clicks.” Not with the Legend; 46 positions should be enough for even the pickiest listeners.
