The email I received from TRL didn't give anything up. They indicated that their work is satisfaction guaranteed and no one has ever been disappointed, ie. taken them up on their guarantee. They've modded many Marantz units but didn't indicate any experience with the Ah!. They also seem reluctant to say what exactly they do on the mods. It tends to go against better judgement to blindly send anyone $550 and not know what they are doing. The many positive posts on TRL mods are leaning me towards going against "better judgement".
