Mapletree 4SE vs. TAD 150 signature best sound???

Are they equivalent in soundstage, bass and treible reproduction?

The Mapletree wins by more than a little. The TAD is a very nice sounding pre,and the remote is handy. The Mapletree is a fantastic sounding pre,but you get no remote. I believe the difference is the use of octal tubes in the 4A SE,point to point wiring,and tube rectification.I'm using a Silver plus upgraded DNA-1

Not familiar with the TAD, but the Mapletree sounds ALOT better than its price would suggest. Made by a retired Professor of electrical engineering, it seems to be a no BS product with a lot of good circuit and overall design behind it. Not audio jewelry on the outside perhaps, but one heck of a good sounding piece of gear.
