As a carrier of the 'audiophile' bug, may I just 'warn' you to be careful of what is known as 'snake oil'? So much about cabling, power filters etc either is in the mind of the listener or if and when it does make a difference, it is inaudible on sub R1m systems. Most decent cables will suffice and outperform twinflex and wire hangers.
Epihany is a good dealership with quality products, but they will push hard for an upsell if they see a gap. Although they seem unfamiliar with Valve Audio, the owner pushed hard to convince me (I forgot the brand) some Italian amp sounds better. He also tried a demo to show the B&W 702 does not sound as good as the 805 bookshelf speakers. Side by by side demo......well, not to my ear. A bookshelf will always fall short on bass and the difference the diamond tweeter does make is beyond audible frequencies. Midrange drivers are identical.
Something I hold against them is that initially they tried to demo equipment while streaming via bluetooth....I immediately picked up something is off - bluetooth streaming is rather 'lossy' and easy to hear on any good system. They took me for a 'poepol' in my opinion. Respect the customer, if he comes to a shop with goods of that calibre, he likely knows some stuff, don't try BS him!
Follow your own ears' and not their ideas is all I can say.
