cost of speakers in relation to the rest of the system

I never thought of my system this way so it's an interesting exercise. MSRP in brackets (where applicable):

tube monoblocks - $3,600 22%
SACD player - $1,000 ($8,000)  6%
analog rig - $3,700 ($7,500)  22%
digital file server  - $3,200 19%
speakers - $5,000 ($10,000)  30%

The above doesn't include wires, tubes, etc., etc.

I never set out to build my system with a particular % in mind, I just gradually upgraded, tweaked and DIY'd over the years.

MSRP calculating is utter nonsense when one calculates the "value" of one's system because in the real world the MSRP is nothing but a figment of the manufacturer's imagination, not to fail mentioning that it's also price - fixing - hello McIntosh?  Weber grills?  It's almost laughable when you "shop" their products - and folks wonder why bricks and mortar retailing is suffering?

There is nothing about paying a manufacturer's MSRP that has made me feel better about buying their wares - shopping for high end equipment needn't be an exercise in discovering  that manufacturers can and often do hold their retailers hostage if they don't abide by their ridiculous parameters, the first and foremost being that they don't sell for less than their imaginary worth. 

Anyway...on point. 

My speakers are Thiel 3.6's mated to a REL T7 sub. Cost ratio?  About 1/3 of my total, with the Simaudio being the biggest ticket item currently. 

It ain't the clubs, Laddie. It's what fits your budget and wows you. 

No one pays msrp. But it works for percentage comparisons 

"No one pays msrp."

Uh oh.  I recently paid msrp for a piece of Schiit, a Bluesound, and a Denafrips....

Yikes !!! Sorry
