For shortwave listening i use a Drake R8A, a Sony 2010, most of the time with many others that mostly sit on the shelf.

I use a wellbrook 1530 loop with the dc block replaced with a modified rf systems dx one control box which contains broadcast band filters and a switchable attenuator along with a rf systems wa50 rf amplifier which will add 10 Decibels when i switch it in. The dx one control box is a 220 volt version i found on ebay and i removed the power supply and used a metered variable power supply so i could monitor the current and voltage while having more filtering. I feel its about as good as i will get for an indoor antenna, I have no tower up here since i moved about two years ago but will have in the future.
