maybe you should open up a design studio fabrication and go into business if it is that easy
Those preamps are nothing special either IMO
Many higher end preamps are dated and ugly, why is this?
Conrad Johnson, BAT, VTL are all very good preamplifiers, they are dated and just ugly. Audio research is a prettier amplifier but it's not very well regarded due to it sounding more like a solid state, ie. Not really a tube preamp despite all those internal lightbulbs.
Cheaper preamps can be more pretty. Schitt makes a pretty preamp for about $1000. People like pretty.
D'Agostino by many is viewed as very attractive but kind of weird.
