what makes a viper so expensive or a bently very expensive. not produced in large numbers, hand built and exclusive. they do sound wonderful when paired with good speakers [i personally like the b&w brand speakers] but very good sound can be had for much less. i heard a set of the ML monobloc amps [25,000 CDN pair] through b&w 801nt [15,000 cdn each] and it sounded wonderful. i have also listened to some wilson audio grand slamm's [120,000 cdn pair] through some krell monobloc amps [± 15,000 each] with a krell cd transport/preamp [10,000 cdn] and it was great... lots of money, but if someone has the coin, and wants the best, that is what is around for people to have. my audio stuff at home is a little less [more like LOT] less expensive, but for the price i paid for it, and the quality i got, i am completely satasfied. [but it still wasn't cheap/inexpensive. . ]
