Sir,
I did not want to comment on this - however, since it has been posted here - I will write just 1 comment on it;
a]
When the price of a component goes up - the performance of it also goes up - generally
b]
If you put 2 different priced components into the same set up - they will sound different - however, just to illustrate - if the 2 DAC's are priced @ 6K & 13K will the 13K DAC sound 120 % 'better than the 6K DAC ?
c]
The answer lies in the rest of the chain.
d]
The Best way to find out is to go 'downwards'
Move from a top end system to a mid fi system & then compare the 2 components.
You will not hear a difference between the 2 DAC's [as I have mentioned above] if you were to play them in a mid fi set up - they will sound very close to each other [say a NAD & a PSB just to shoot off a name] - the 2 DAC's of 6 K & 13 K respectively.
e]
When the overall quality of performance of your set up goes north - the source too needs to go north & then what people call diminishing margin etc. comes into the equation;;;
All said,
top end components - need top end partners for them to show them selves. I have experienced this 1st hand - several times.
The biggest problem is - assume a persons audio set up is a solid 7/10 & he has to audition 2 DAC's - 1 of them being a 6/10 performer & the other being a 9/10 performer & the difference in price of the # 2 is 300 % ++
When the 2 DAC's are played - the difference cannot be heard - simply because the systems overall ability is a 7/10 - The final flow of the pipe is 100 % dependent on the narrowest part in the tubing [maximum pressure - minimum flow] !
However the same DAC's if were compared in a set up that played @ 8.5 / 10 then the diff would be stark & it would not take long to decide what one needs to get.
Therefore I say :-
System Matching
Budget Allocation
Maximizing ones room & components
This is all very very important.
Buy all components that can work with each other & compliment the performance [up lift the overall performance]
It is a 'team-effort' & if you have 3 star runners & 1 slow person in the team - the chance of that team doing well gets diminished a lot;
Just my 2 bits - sorry for the long post.....
Conversely if you add Usain Bolt into a 4 X 100 relay team with 3 runners from a collage level sprint team - that team will not win the National Relay; Yes, UB will run faster than all others - but he cannot make up for 3 slow runners that loose 3 seconds per 100 meters against the other National Level Runners - so I feel - sorry for the obscure example...
