That's the problem. The wallet will work for the D4, DTC-9.8 and SMS-1 in one fell swoop, but I don't want it to. Restraint is HARD.
Re: Epos - The Epos bookshelf speakers were actually my wife's number one favorite of all the speakers we auditioned. I was not as impressed with the Epos towers.
Re: Usher S-520 - I've been wondering about some specs on the Ushers that I'm not sure how to interpret.
Sensitivity: 86dB/1M
Impedance: 8 ohms nominal
Power Handling: 50 watts
The way I read this is that it's not a very sensitive speaker and at 86 dB. It's going to want some power to drive it properly. But then they rate it at 50 watts power handling, which leads me to think it will shred when fed the juice that it's sensitivity suggests it needs. Now I understand that most of the time it will be handling just one or two watts, but it seems to me that transient peaks could easily easily overwhelm this speaker (especially if using a receiver that could send out clipped peaks when it runs out of power supply).
It appears to be a damned if you do, damned if you don't situation. The sensitivity would demand that it be driven, but the power handling suggests it's somewhat fragile.
The UK HI FI world review addresses this issue:
"The nominal 8 ohm impedance and reasonable sensitivity will ensure wide amplifier compatibilty..."
In the measurements they claim that impedance never dips below 7ohms and that "the Ushers will not be difficult to drive".

Also, Chris Martens from avguide.com actually compared the Usher directly to the Epos els3 (which are/were high on my list I might add, and the M5's look great but are a little more than what I want to pay) in his review of it and said that he found the Usher's can: "handle heavily modulated passages and fast-rising transients...with much greater freedom from compression or constriction than their competition." He goes on to say that: "the Ushers managed to play cleanly at volume levels where the Epos els 3 where starting to show traces of audible compression." That review can be found here:
http://www.usheraudio.com/news/Poland-S520.pdf (I think I already included this link before, and ignore the "poland" thing, it's in English).
So if the Epos which have 4 ohm impedance and 87 sensitivity (right?) can play well loudly, and the Usher's can beat them out (according to this guy at least) at this, then I don't think the Usher's specs are a problem. I've also read that they sound great loud or at low volumes. I prefer moderate volumes anyway, if I want to crank something I'll use my BIC's.
But anyway, like I mentioned, I have a vintage Pioneer receiver and I've heard that back when it was made (late 70's) wpc were measured honestly or differently than now. So although it "only" has 80wpc, it is very loud and powerful, and if it were measured today would have something more like around 120-150 wpc or even more. I know it's as loud or louder than any of my friend's newer high wpc receivers or amps (we've hooked it up to their systems just to see how it would handle them and on two channels playing anyway it usually is louder than the newer equipment or at least as loud), and it literally kills my early 90's Kenwood reciever which is measured at 80wpc, it makes it sound like the anemic wimp it is. Actually, I have a smaller vintage Pioneer as well with "only" 35 wpc and that thing at least matches my Kenwood with supposed 80wpc.
Either way, I could always upgrade with a larger vintage receiver or amp (they made some insane ones that went up to 200 wpc as measured back then, you can find some info. on those here:
http://jbmanuals.free.fr/web/monsterreceiver/ ) or even a newer one, though I prefer vintage components.
