Hi dumbeat,
Stage 3 Concepts. I was lucky and was able to get a free audition from a buddy who had already purchased it. When I knew I was ready to make that commitment, I bought Used for about 50% off MRSP.
From what I read you already have great components. Just need to maximize their operating potential.
I began with one Stage 3 Concepts Kraken from the wall outlet to a Passive Power Strip, back then it was Oyaide R-1. From that power strip I ran Silver Oval 2 power cables from Analysis Plus to my components.
When I was able to find another Stage 3 Cable, in this case Minotaurs - a step down from Kraken, I replaced the Analysis Plus Silver Oval 2s with them. I started from the source/ CD player, then the Pre amp, and finally the amps.
It took several years to source these out and I am still trying to get into a pair of Stage 3 PC for my Subs.
I am currently using the last two Analysis Plus Silver Oval 2 on those. Know that with each Upgrade there were remarkable differences. It takes some patience for sure, but well worth it.
The way I look at it is the investment I have made over the years in Power Delivery has been able to maximize the performance of my components and speakers. This
substantial
investment has come in at a fraction of the price of what some of my rich friends have spent on full blown out 500K - 800K systems. In some cases twice over.
Naturally I have made comparisons, and I will say that Musically, my system is just as good if not slightly better than the 500K systems.That assessment is mainly due to personal preferences and choices. When it gets up to the 800K systems - admittedly they are better, but certainly not 90% more $$$ better. Where all these systems really excel is their commitment to ergonomic design / packaging - Really Sexy looking gear that blows away my stuff. I would give my system a 6 out of 10 for looks and its probably a bit lower as no parent ever really wants to admit that they have an ugly kid - no matter how talented.
I hope this helps you out
Enjoy the ride, Its not a race..
