Hi superkat,
I have similar problem to your Lino C3.3. After playing on one side all ok, then on the side, I start getting signal dropouts that gets worse.
I opened it up and sure enough, the bettery is fully charged. I don't think it's the charging circuitry since the battery is fully charged. Must be something else going on. Weird that both you and I have similar issue.
Looks like I have to start looking at alternatives. There's the Mofi Master Phono with transimpedance input at $6k and with XLR inputs. Seems like it has good reviews. But not sure if it's better than the Lino C3.3
And thanks for your inputs and also review of the Sutherland Dos Locos. Seems like an upgrade to the Lino C3.3. I don't mind spending a bit more if the sound quality is positively improved. I just hate to go backwards. Life is too ahort.
