Hi,
i am a happy owner of a Cornwall III and try different amps at the CW.
My first and best amp for the special houers is the cayin a88t (modifired)
My everyday-amp for some years was the old Harman Kardon hk 660. Sounds beautyful with the CW - realy. Now he is broken and i looked for a new evryday-amp and chose the Magnat MA 800. He is a realy good parner for the CW but you have to chance the 2 tubes. Give him the psvane 12AU7-T and you will be very happy.
Greetings from Germany
