If you can find a used TRL DUDE preamp, the sound is without compromises and the bass is just awesome--tube or solid state. It is a tube preamp with a very stout power supply. Read the online reviews. There are many. No phono section, however. The DUDE is a large unit (75 lbs.) and has RCAs only.
The MW preamps are also very nice. They will not equal the DUDE in sound quality.
