Is there a magic formula for spending on components in a system

System synergy is hard to achieve but attainable at almost any $ figure - if I were a deep pockets retailer I would have say 5 differently priced systems with synergy I had verified in an untreated room. Many customers, maybe not quite most, would love to buy synergy without the cost of experimentation. My own journey to system synergy has been EXPENSIVE, I wish I'd found a shortcut sooner!

Anyways just my 3 cents.

My journey cost me peanuts....

Simple listening experiments+homemade materials or low cost electronic one.....

Read my thread for shorcuts .... :)

My main system; mostly used items except Dac and power cables:

Amp 30%
Speakers 25%
DAC + Power Supply 25%
Source 5%
Interconnects 10%
Power cables 5%

Not big into formulas, but I am big into what sounds good and works well together. 

Magic formula is simple.

Spend right up to your limit...or to all you can afford...and you'll be there.
