Though Ralph(atmasphere) is too much of a gentleman to say it, I will- An Atma-Sphere preamp would be a great addition to your system. I would contact him to get advice on which one would be compatible with your system. Though I think one of his UV-1's might be a good match, and very affordable. There was one for sale here, but it expired. Maybe the seller still wants to sell.
If you love your current Maggie's, I would not change them.
