I have recently purchased the Nite series IC's and digital, also Signature power cords on all other components (5 total), plus the Reference speaker cables. The combination is simply fabulous! Every aspect of performance is enhanced. The removal of electronic "hash or artifacts" is removed---if you have not experienced this effect, it is remarkable. The pricing is extemely reasonable and much better than the "big" names. If you are on a budget--start with power cords on your digital, then go to power amp, then preamp. Next do the digital cable, then interconnect, then speaker cables. I can guarantee you that you will not be disappointed!! Plus, you have a money back guarantee!! There is no downside. Rick is a very nice guy -- and not in any way high pressure.
