If it is in your price range the Graaf 50B that is for sale is a very very good tube integrated ....I have no affiliation with the seller but used to own this model and if not for going to much more expensive seperates I would not have found any real improvements. It is also great looking and built well.
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.
