Next Biggest Improvement after Speakers ?

It depends what you are trying to accomplish. There have been many good comments made so far.

Everything in the system is important, but IMO speakers are the least important. All they do is reproduce what comes to them. They do not create signal! They will not add back into the music what was lost coming down the line.

The most important thing in a system is the room. Nothing will sound good in a bad room. It doesn't matter how good the system is if the room keeps it from being able to reproduce music. Make sure the room is good.

Second most important thing is the source. CD, SACD, Vinyl, cassette, 8-track or tuner. If the equipment with which you procure the music doesn't get it off of the source it is lost throughout the chain. Get the best CDP, or Cartridge you can justify and get the most from the source!!!

Third, follow the signal to the speakers. Cartridge - arm - TT - cable - phono stage - cable - pre-amp - cable - amp - speaker cable - speakers.

Every piece will effect the signal. Buy pieces that cause the least detrimental effect on the signal. Make sure as much of the signal taken from the source arrives at the speakers as possible. If a poor signal arrives at the speakers they will reproduce junk, if a good signal arrives they will sound good.

Speakers are important, but they are the least important thing in the room. Get good speakers, but make sure the equipment upstream is worthy of them.

I myself started off purchasing the speakers first because I new what I wanted, to build my system around them. I already had a pretty nice amp and knew I could live with it and get a new one later, besides I believe that an amp could only change sound so much. The next thing I bought were some nice Cardas Cables and noticed a slight improvement but not enough to consider it a dramatic improvement but it was favorable. I should note that I have B&W 804N Speakers which are known for little bass but I wasn’t worried because I have a pretty good subwoofer. The next thing I wanted to get was a pre amp. After reading a lot of articles and had somewhat of an understanding what type of sound I was looking for, I purchased a Pre Amp, a tube pre amp, a Cary SLP94L. This component changed my system more than I could ever have imagined. So much that I don’t even need my subwoofer any more, the bass is perfect. Its exactly what I was looking for and is so quick. I never new what quick bass was until I heard this preamp. It really gave me understanding of what was being discussed in these articles in magazines and in Audiogon. The highs are midranges are superb as well. I can only imagine what a new amp will do but I don’t know if I need to improve on what I already have. If I do I can’t wait to find one that I want.

source is paramount you can not improve anything downstream
without addressing the source first. then the speakers next.

How come no one mention about the CHAIR :(
