I had Mike at Austin Stereo do a full refurbish of my C28. He recapped it, fixed the grounding issues, and got both phono stages working again. Some fresh bulbs and a little elbow grease and it's looking sharp, too. Wow! I had no idea it could sound this good. Considering there are so many adjustment dials that could affect the sound, this thing is surprisingly transparent and very easy to listen to. I haven't really missed my Audio Research SP-6B that much, either. I'm planning to bring my MC2505 to him next. I'm very happy with the sound of that amp, but I'm excited to think how much better it could be.
