Anyone experience any Op amp rolling?

More and more devices (DAC's /Amps) are being offered the ability to change out different Op amps. Easy as changing a tube. Op amp can alter the sounds noticeably. 

In an effort to keep the cost of an item lower the manufacturer frequently uses very inexpensive IC op amp chips. Many less than a dollar. It would seem a good upgrade could be had using a more expensive discreet op amp running in class 'A'.

Anyone have any experience with the newest Burson V7 Vivid or the Sparkos ss2590 pro? Both units run in class 'A' mode. Two top tier units, both run over $80 and I find the improvement in sound remarkable and greatly improved and well worth the $ spent.

The reply thing isn't working.  gdaddy1...are you saying you actually rolled yours?  One thing I've wondered about is power.  Is it affected by being in class A mode?  Can you comment on differences in the ones you tried?  I've seen those you mentioned and was curious if worth it.  Thanks for the post and in advance for a reply.  :-)

@gdaddy1  That's awesome on the class A part!  I've heard a lot of good things about Geshelli Labs.  Their stuff is quite different it seems.  I might have to bite the bullet on at least one (pair) of the Sparkos or Burson chips.  Maybe the Sparkos first based on @olds1959special 's comment.  Thanks olds!

Thanks for the link!
