I would also be very leery of advise and opinions from audiophiles who really don't know what they are talking about.
Bruce Moore is one of the best audio designers out there; and a tube audio pioneer. His preamps have been very favorably reviewed. The Uranus 2, if I am not mistaken, was a TAS favorite and competitive with the Conrad Johnson Premier 2 of the time. Also, someone refresh my memory please, but I think he may have been a co-designer of the original Modulus preamp,; in fact, I think the Uranus was manufactured by Audible Illusions.
I doubt that the unit, if in good shape, is anything but very musical. Good luck.
