I have a pair of the original RF-7's now for about 12 years. These are large speakers (their size is part of the reason for the very high 101 db efficiency rating). The high efficiency provides loud listening levels in my 16x22 foot living room with large openings into other parts of the house. I'm driving them with a Super Zen.

These speakers need room to breathe. The front of my speakers are approx 4 feet out from the front wall. With the Super Zen these speakers disappear and provide a wide sweet spot, but you need a big enough room to allow for ideal speaker placement.

These speakers are very detailed allowing one to hear even very subtle changes to upstream components. This is very useful when tweaking the system.

They can sound sharp and grainy depending on the upstream components (especially with some solid state amps). This is not a fault of the speaker but rather a strength IMO. The Super Zen and Oppo combination I use really sound good.

With only 2 watts driving them the RF-7's alone do not produce live levels of bass. I use the HSU Mid Bass Module in combination to achieve a great low end at all volume levels.

I suggest you consider a Mid Bass Module to go with you RF-3's first. You will be surprised how much more power and soundstage are added for the dollars invested.
