Thanks for all your help Guys.
I've decided or rather I have already purchased some Good as new sr60i's from Ebay . I know because of the experience with my igrado they have a attractive sound I will appreciate.Also that they are mod-able is a fun way to experiment and as mentioned personalize the sound signature a little and or learn a little about headphones .
Eventually I'll look out for some second hand HD650's and see how there signatures compare . If I prefer the grado signature I will try and visit a Grado stockist & compare a more expensive model Against my modded RS60i's .<<< well that's the plan anyway :-) .If I prefer the HD650's then I'll stick with them but maybe I will enjoy the differences these two makes of headphones offer .
Anyone listen regularly too senns HD600 or 650 and Grado's SR series of headphones or do most choose on or the other .
These "Good as new" SR60i's I have bid for have turned out to be SR80's without the "I" .
Have I been hoaxed or as the seller is suggesting have I in fact got a upgrade as there 80's and not 60's.
Are the SR80 (I assume they will have holes in the pads) as Good as SR60i's .
