Ditto the Pathos. Audiomat is a very good all-around tube integrated, but the bass might be what you are looking for, even though the lower mids make up for it.
Tube Integrated with deep bass
As the subject states I'll like to know of any good tube integrated with deep, tight bass. To some this could sound like on oxymoron but the truth is some Vintage equipment do have deep bass. I'm looking for new equipment, no vintage.
