Building through the mail???

Being in a small town I have no dealers I can audition products through, and travel for me is quite difficult with job, kids etc... So, after a couple months reading all I can here as well as other sources, I've decided I'll have to mail order everything and hope for the best. This is my first attempt at hi-fi so I'm almost positive that my ears will like it as I know no different.
I'm not going real big on the spending as I cannot afford the high dollar eqipment.
Here is what I think may go well together:
Roksan Kandy iii int. amp with matching cdp
Paradigm studio 60 v3's
A pair of Paradigm servo 15 subs, or Velodyne DD15s
I am hoping for a mild top end with the paradigms, and some spl in the room(the reason for 2 subs).
If you have any advice for me I'd be more than happy to here from you.

Roksan can be had on here for absolute bargain prices, I had a cdp and it was pretty decent.
Good luck. You are in a tough position. Just so you know - and I am stating this only because I am certain of it - you will not get a mild top end from Paradigm, especially from nearly all mid-level electronics. Unfortunately hot high frequencies are really the bane of popular gear at your price range.
Two 15" servo subs? wow, you must want all bottom end!

You can make decent decisions without audition if you do your research beforehand. if you list your budget, room size, and listening preferences you'll get far more valuable commentary too.
Just so you know, we were all there at one point in time.

My advice would be to forget the subs. Use that money to put toward one of the other components (the amp would be my choice). Either buy speakers that give you everything mid-fi (PSB Stratus Golds) or hi-fi in a monitor (Usher or Totem Model 1s).

Educate you ears to what hi-fi sounds like. As the years pass by, upgrade, upgrade, upgrade.
The Polk audio LSi 15 is an incredible speaker that will pair well with the Roksan gear. The polks can be ordered from crutchfield and they come up sometimes both here and on ebay. At 1500 for the pair delivered from crutchfield I still think they are a great deal. They have sweet mids, smooth highs, and awesome bass. I should have never sold mine.
Unless you're building a home theatre, or have a very small pair of monitors, I always suggest it is better to have a good full range speaker than a speaker with subs added. I would save the money and not buy the subs at this point.
What are your speaker and listener placement constraints (distance to front/rear and side walls, distance to speaker)? What's the room size? What are the acoustics like (lots of reflective surfaces, shelves stuffed with books, etc?)

Speakers designed for your intended placement near or away from walls are required, because if you don't take that into acount you can turn a speaker that would be +/- 1dB into +/-10dB which is not high fi.

Speakers with a lot of high frequencies in their power response are not going to be pleasant in a reflective room.

Anything less than a 3-way (a single "full range" driver is really a mid-bass plus a tweeter with a mechanical cross-over between the two ways; the same in a back-loaded horn has) will suffer from midrange IM distortion problems when you combine bass with realistic output levels.

This includes the 2.5 way Studio 60s and even monitors with healthy 7 or 8" mid-bass units which are just getting to be sufficient mid-bass drivers.

Adding the third way in a separate box with an active cross-over buys you a lot - you can place the main speakers far enough from the wall so that the SBIR notch is out of their passband, sub close enough that it's always operating into quarter or eighth space, main speakers where they image bass, sub where it has better modal behavior, etc.

You don't want a ported speaker though. To get good integration with a ported speaker you need to cross it over an octave over the port tune so the port's not contributing bass, but it is leaking out-of-phase midrange energy. A sealed 2-way with a healthy sized (7 or 8") mid-bass would work better. Pair it with a 2nd order butterworth electrical high-pass and 4th order Linkwitz-Riley low-pass on the sub.

You'd also be better off putting more money in bass traps and less in electronics.

Finally, you might shop the used market. If you get something which doesn't suit your tastes you can sell it for what you paid less shipping costs and try something different.
