I agree with Kkirkpa don't do anything rash - I would work to get the best out of what you have first. There are a lot of things you can do to take the 'edge' off of your system. I have had GREAT success tuning my system with Bybee products and Black Diamond Racing Cones/Parts and the (ridiculously expensive) Shunyata power cords. It is amazing how far these things go to improve the sound and take the edge off of what sounds like a great system. Why throw away a group of components you found and like? Things like the stand they are on, and power cords can really make a big difference. I would contact DJ at BDR to get his advise (he's a no BS guy who will tell you if he thinks it won't help) and then borrow some cables (the Cable Company is good for this) and try to find ways to 'tune' what it sounds to me is a sound you are basically happy with. I have a Meridian 508-24 and Pathos Twin Towers and I too was surprised to find CDs somtimes sounding a bit hard compared to my VPI MK4. $8-grand is a lot of scratch for system; I would focus on taking reasonable steps toward cleaning it up before I started swapping major component out.
It's not the sound I want!
My system consists of a Krell kav300i, Aeriel Acoustic 6s and AdcomGCD750. I have Cardas cables , Jenalabs interconnects and Synergistic Research ac chords. It sound great at times but I find many cds hard to listen to. I listen to vocals with acoustic guitar and the guitar sounds detailed but so metalic and unnatural. It sounds like sombody is playing a saw with a bow. Is this what digital really sounds like? Is it sytem matching? I dont think it is the speakers. Is it just a matter of settling for the best we can get for $8000.00 and limiting what we listen to?
