I would certainly match $7500 speakers with a $2500 rig! For one reason, it seams to me that a system is best built around the transducer, blow the first wad on the speakers and upgrade as necessary later. Also- money isn't everything. There are some great products which don't cost a fortune.

The problem is that you are going to get a super revealing speaker and a less than high end (dare I say, crappy in comparison) source. Go buy a pair of Wilsons and drive them with a lesser source and you'll have a system that will not be satisfying because the Wilsons will faithfully give you every flaw in the upstream components. My experience, limited as it may be, is that when you achieve balance throughout the system you will have much greater satisfaction. I have yet to encounter any anecdotal report that a $2.5K front end is going to adequately drive a $7.5K transducer. On the other hand, a 4-5K set of speakers and 5-6K in amps, pre, source and wires will be a much more balanced system. Balance your investment throughout the chain and you'll get a much better result.
I used 10K as a round number, but if you look on audiogon and audio asylum at the various systems, regardless of the total system cost, you find a balance in the quality of the components selected. I jumped on that 75% rule because I think it's poor advice to draw a line in the sand like that when it cannot be defended by even the most cursory review of the reported experiences within the community.
Any opinions on Jolida products? They have some nice looking units in my price range, both tube powered and hybrids.
The Jolida units get good reviews. I'm thinking I'll get a 1501RC for my office system - integrated for simplicity and the flexibility/fun of rolling tubes in the front end. I've always used CJ gear at home, but I've heard the Jolida gear in a local shop and it sounded really good on the Spendors. I've not read about any issues with relability. If you are nervous about getting tubes or can't afford enough tube power to properly drive hungry speakers, a hybrid is a great starting point.
