Sorry about the confusing comment about the Rada and tube gain as that is voltage. At times I get typing faster than the coffee has entered my head. Yes, I get up late.
I really like the Hagerman Trumpet too. That is very inexpensive. The Lino is much more quiet.
I actually look at the Rada Solypsa has for sale and consider getting it because its so good and very undervalued at the price he is offering. I would then try and wrap the entire interior in copper plate to block RF induced hum. I sort of doubt that would work. But I don't know.
I had bad hum with a SUT I bought to use with a Denon 103R. I wrapped the cable in 2 layers of mylar and drained one end with dead soft silver. That shut 90 plus percent of the noise out. But RF is tricky. It could enter anywhere and its up to the power supply to deal with it. Or so people like Rob tell me.
Rada a different sound from the Lino. I think the Loco was much closer in vinyl reproduced sound to the Lino than the Rada.
