How old is too old ?....

Craig, you're giving away all my secrets! By the way, you really need to build a set of these. They are awesome. And that "comb filter" thing is way, way overstated. Walking bass lines are no problem, amigo. I have no urge to make other cabinets at this time.

Jvia..you may not be tooooo far from the true.
I just maybe looking for a excuse to update.
I still have and I am listening to the kefs,as I type this reply.
The reason I have itchy fingers and am looking to update ,is the improvement in sound was SOOOOO unbelieveable with all the other updates ..why stop here!!
My biggest problem is I am very isolated and it is impossible to listen to other speakers.
I know trust your ears but it isn't possible for me.
So all advice I get helps me make that decision.
All my updates ,to date..no pun intended,have been made with
info supplied to me ,from forums such as this.

If you want good sound for the money, check out the Meadowlark line. The new Swifts are running hot competition for the highly regarded Kestrel Hot Rods that many Audiogoners have liked. The Swifts are only $995 a pair. They are alot like a Voigt Pipe with a tweeter added. You may be able to get a pair shipped to you with a money back auditioning guarantee. This is not the "ultimate" speaker, but it is a very good musical value for the money. A lot of folks have used the Meadowlark Kestrel Hot Rods in some pretty expensive systems, and the Swift is very close to them. Some even like the Swift better. It uses their latest design that will eventually be used in the other speakers in their lineup. Also, they are all wood, and have a nice look to them. Check out their website.

Lots of good replies here. Last year I bought a set of Infinity IRS Betas. Originally introduced in 1988. Mine are late production, though I could care less. I've wanted these since new, only pricing kept me away. I'm fortunate in that here in Mass good high-end stores are not far. In fact, just the other day I had the pleasure of listening to M-L Statements on an all-Boulder front end in a proper room. Did I like 'em, sure! My system with the Betas is just as satisfying to me. I remember when I had to have that next "bump". Now I've been satisfied for quite some time.

AFAIC, if you have the desire for new, please attempt to listen before you buy, even if it is difficult. I've got a feeling you'll have to spend way more than you would like to better what you have now. I think it's great that your frontend improvements have been immediately apparent to you with your Kefs. I would upgrade the crossover caps as another poster suggested.
