I've actually only tried KT88s in the SLI-80 and SLI-80HS. I've tried these in EH and GLs and much preferred the GLs. I recently inquired with Cary about bias settings should I start to experiment with other output tubes and interestingly they suggested that KT120s would be a notable SQ upgrade over the KT88s in the SLI-80HS. At some point I will try these.
