    Well after a nice 700 mile round trip I finally collected them the case work is out of this world . The KT88 turned up this morning here a couple of pic`s offmy phone I will dig my dslr out in the week .



    The power supply


    And the most important bit the sound after the first hour they sounded really good after the five hours totally gob smacked they just seemed to improve hour after hour ,The bass is deep but so clear the midrange and vocals are in a different league to my old amps a pair of Arcam p8s .
    The sound stage is massive just fills my room ,the speakers are Ditton 15xr`s that have had rebuilt crossovers how can a sixty quid set of speakers sound so good I have no idea Jason who built them for me said they will settle in over the next couple of weeks .
    The acid test SWMBO listened to them tonight and the comment was jesus thats sound`s good how much have you spent LOL
