I'm currently using the ayre p5xe with my DMC-30SS and have recently installed a Lyra Kleos. I'm really enjoying vinyl. For some time I have thought that my phono stage was a potential for better performance. I'm beginning to look into upgrading the phono stage early next year. On the short list would be: Einstein, naim superline, ARC PH8, Artemis PL1. I'm open to other ideas. I would prefer a single ended design as the balanced input is taken by my digital source. Can anyone comment on pairing phono stages with the Spectral pre? The DMC30 has a input impedance spec of 15k ohms. The Arc ph8 states a lower limit of 10k ohms. Are tube phono stages a bad idea with the Spectral preamp? Has anyone heard the Tempo electric phono stage? I have my fingers crossed that Spectral may introduce their own phono stage when I'm ready to upgrade.
