Thanks for all your insightful responses. So it seems there are 3 general suggestions. I will try to address each of them and provide info for more dialogue.
Changing speakers:
I hadn't given this a thought. I agree, the Vandersteen arguably gives you the best "bang for the buck" if you will. Yes, I would have to spend quite more money to better that, but despite my reservations... I'm saving for an engaement ring, I can budget up to $2000 for new or used speakers. My listening room is roughly 25 x 15ft, and my system can only fit along the longer wall. What are some suggestions? Anyone own Gallo reference 3/3.1, or can anyone comment on them? Are there people out there who switched from a 2CE sig to a 3A sig? What improvements did you hear?
Keeping speakers and re-evaluate/re-calibrate listening perception:
Krisjan and others make an interesting point. It is very possible that my listening perception or preference has changed/skewed due to listening to music through other systems. However, I am also inclined to think that my listening perception has been somewhat improving throughout the past couple years. In the past couple months I felt that my old NHT/Rotel system (my first "real" system) was very listenable, albiet a little lean. The Sennheiser HD650 headphones were driven straight from the phono out from my Eastern Electric CDP. It's sound is wonderfully flat throughout the mid and high FQ, but the bass can be overwhemling at times. Just two years ago my NHT/Rotel system was the best I had heard, well that was until I auditioned the Vandersteen. I hope my listening perception doesn't flip-flop so easily, but perhaps a recalibration is in order. I will keep your comments in mind when I listen through my current system. I would like to hear more of your thoughts.
Keeping my current system and making minor tweaks/additions:
Eagleman, thanks for your comments on tube rolling. I could be wrong, but I remember an old post you made regarding "high FQ roll-off" with your system. What changes did you end up making?
I am quite a novice when it comes to room treatment. I would like to learn some more about this. Can anyone direct me to a good thread or website?
I will test out different speaker placement this weekend.
Thanks for the cable suggestions. I'm gonna have to start demoing some new cables before I conclude I must change them.
Wow, I started out with what I thought were alot of qustions, but now I have even more. Thanks for all the comments... keep them coming.
