It is, although the amp's an 8vs.
For some time I'd had a nagging fascination with Cyrus kit, mainly because it comes across as a real Marmite product. Anyway, one evening (after a bottle and a half of Medoc) I bought the amp off eBay...and sod the buyer's remorse in the morning
And you know what? It was/is really good, much to my pleasant surprise. The PSX-R adds a decent degree of weight to the overall sound (although it's good to start with) and never at any point do I feel the set-up is adding any character of its own, it just gets out of the way. Owned it for nigh on 3 years now.
