i have yet to hear anything better but keep in mind i used very expencive parts. all riken ohm resistors, black gate caps, alps pots, and pure silver wire. the tubes are also rare...especially all the tubes [except for the middle one..thats the most expencive so i got a cheap one] but the small one with the red base is extremely expencive..so is the the other one.
you need to keep in mind that they are not very powerful but will sound good provided that you have good speakers. also...they are very fragile [broke my little redbase ~150$ in transport to school] but its very rewarding experience to build and listen to soemthing like it come to live.
