I'll be doing the vast majority of my listening with digital audio through my new Nova. I've had Audioengine 5 speakers for the last 2 years, and I enjoy them, but I'm looking to be blown away while using the Nova and some nice budget bookshelf speakers. My list includes:
PSB Alpha B1 (or other similar PSB's)
Wharfedale Diamond 9.2, 9.1, 10.1, etc.
Wharfedale EVO2-8 (for $320)
Infinity Primus P162
Ascend CBM-170 SE
Mordaunt Short AVIANO 1
Tannoy Mercury V1
Various Monitor Audio's
I was leaning towards breaking budget a bit for the Mordaunts (reviews just seem to stand out for them to me) but I can get the Epos ELS3 for $175 used right now, and I'm thinking maybe that's a nice first step, and then I can save up and spend upwards of $500 in a few months. I should also add that these will be (for now) used at a desk on homemade speaker stands, with their backs to a wall a few inches away. They wont need to be played real loud, I'm mostly just going for synergy and a real step up from the A5s into hi-fi audio. I bought the Nova because I'll be taking advantage of all of its inputs and I wanted a decent headphone amp for my Grados and Beyers.
