you hear very little about isol but isotek have been bringing out some superb stuff and are pretty big now . as said before , i wish it was not so expensive .
when i had a puresound L10 i put the isotek syncro on it and you could really hear the change .

ou might slip, you might slide, you might
Stumble and fall by the road side
But don't you ever let nobody drag your spirit down
Remember you're walking up to heaven
Don't let nobody turn you around
… Walk with the rich, walk with the poor
Learn from everyone, that's what life is for
And don't you let nobody drag your spirit down
