I'm a Dahlquist fan myself, and have heard most of them. The DQ-28's are not my favorite. The sealed box DQ-20's and 20i's (bi-ampable) are much better IMHO. If you're on a budget, I'd look for a pair of the 20i's, upgrade the caps, refoam the woofers and you'll have great speakers - Even more power hungry though.
re: The amplifier question in your System listing. I have had many, many amps - and run Dahlquists on many of them. The Carver TFM's, while not an audiosnob brand, were among the sweetest sounding solid state amps I have had in direct A/B testing. You could move up to a mint tfm-35 for around $400 on Ebay, DQ-20i's for around $600 and have mucho power with great sound for $1000. (Also as I'm sure you know, if you're only running a CD player, the tfm's don't require a preamp.)
