whats the best addition u have bought for system

Best addition to my system: 700 LPs for $500.

You wouldn't believe how much enjoyment in listening I get ;)

A high quality tube amp. For me it was my Rogue Stereo 90.

What is your budget now and over time?

Flyin2jz, from where you are today you might consider any of the following as next steps:

1. Dedicated AC lines from your circuit breaker to your equipment, if you have an option to do this. I'd definitely do this before spending money on any power conditioner.

2. Experiment with your speaker room placement to make sure you are getting the best sound from them of which they are capable of delivering. If you have them back against the wall, try moving them out into the room. If you have something large in between them, try clearing out that center space. Watch for room symmetry and listen for reflections and seating location. Do some reading about speaker and room positioning, but experimenting is most important.

3. Pay attention to your cabling and try to position them so you don't have cables tangled with each other and don't have electrical cords in parallel with signal carrying cables. Check and clean all of your contacts (electrical and audio); isopropyl alcohol from the drug store (92% or more pure, with no additives) works very well.

3. Consider a separate amplifier, while continuing to use your receiver as the control unit (preamp) for your system. Keep in mind that amps and speakers should always be considered jointly with each other, so either match to your current speakers of be sure what you choose will match well to future speakers you're likely to consider.

4. Pay attention to your own listening priorities and make changes only a little at a time, staying true to your priorities. Work always towards neutrality with any component you add, being careful not to start buying equipment based on balancing colorations against each other (warmer, cooler, brighter, not as bright).

5. Listen to other people's systems. Listen to the systems as a whole to develop a better and better idea of what is important to you. Use complex music for listening, not just single instrument or small ensemble or a singer. Read Lloyd Walker's article on listening and the evaluation process.

6. Have fun.

Cant single one thing out when you are talking about a system but the Coda pre amp works out perfectly.
