I've had a AI2 d for 6 years and no problems at all. The 3a w/phono if you need it can't be beat. Most pre-amps in that price range are solid state and that is enough to make your decision right there. I think you would find greater pride of ownership in a tube product vs SS.
Audible Illusions: how good really
How good is the Modulus 3A really? I am thinking of getting a Simaudio Moon amp with either the 3a (cheap route) or maybe something a bit more expensive, say the Moon P-5. So how well does the 3A really stand up to these 3,000.00 plus categories of preamps. Anyone have any thoughts.
