Well this is my budget system. I live in an apartment, with limited space, and I wanted something mainly for music. I upgraded the tubes in the pre/amp section of the Bada to GE 6189's.Placed a Grant Fidelity B-283 tube buffer between the Emotiva ERC-1 CD player and the Bada. I upgraded the tubes in the B-283 also, and the sound is unbeliveable at times it's so right. I've thought about upgrading the baby maggies to QR 12's or 1.7's, but they really seem to work well with the equipment and the space. Maybe at some point I might go up another level to the Bada Purer 3.8 Hybrid Amp. I'll keep thinking on it. but right now I really can't justify any changes. I will add pics when I get a camera.
