I know that any of the amps I am looking at pushes more than enough volume.
And any closed back amp should be able to provide the bass I need...I also have no intention of parting with my cash until I have test-driven each of these amps for a few more hours.
thanks for your advice tho...I am begining to lean towards the Tsl602 and the 5150...now throught to the stores tomorrow to decide which one.
