Advice on going from mid level to high end


There are a bunch of advice threads focused on how to assemble your first system. I'm hoping to get some advice on making the move from an established but still affordable system to something that's more high end.

Like most people on this site I've always been interested in music/audio. I assembled my first more serious system about 7 years ago, buying much of my equipment used over several years. I have a dedicated room and my current set up is:

Polk LSi15
McCormack DNA-1
TAD-150 sig preamp
VPI scoutmaster
Cambridge Audio 840C
Cables include a mix of Shunyata, Harmonic Technology, and Analysis Plus

I think it's a great setup but I've been fortunate to hear a number of very high end systems and would love to move up over the next few years.

For those of you who've made the transition from a $5-6K system to a $15-20K system, what advice do you have for the uninitiated?

Many thanks.

The best move I made was to listen to as many systems as possible to learn what I needed. Then go to an audio show to hear 100's of speakers over the course of a weekend. You'll at least come away with 3 brands to investigate further...and eliminate others no matter how popular they are in audio circles.

To me the speakers will determine the right amp...then the amp will lead you to the right pre amp and so on. To start with amp or pre amp would then dictate the speakers you can choose from and that is putting the cart before the horse.
consistent with the previous posters, i'd look first and foremost to upgrading your speakers. you have excellent amp/preamp/sources; my sense is the polks are your weakest link. there are numerous threads regarding the best speakers in the $3-5k range and beyond; i personally like psb, vmps, revel, proac and von schweikert, but go out and hear what moves you.
Agree with previous posters: time to go listen to some speakers. Good luck and have fun.
I'm with those who advise on room acoustic and speaker placement treatment before looking to upgrade your components. I owned the LSi-15s a couple of years ago and believe they perform above their price point.
With a poorly set up room you'll never achieve the best from any speakers.
