Primaluna & Klipsch Cornwall frustration HELP


Well this is a little frustrating. I have a Primaluna preamp and Primaluna Dialogue 5 power amp. Found a great deal on some Klipsch Cornwalls. Heard Klipsch and tubes were made for each other. Hooked them up and it had very little bass. I was expecting a BIG sound. Sounded almost anemic. Hooked them up to a class D audio amp through the Primaluna preamp and it was fantastic. Lots of slam. A great rock and roll sound. These are very efficient speakers so I don't get why they don't sound good through the tubes. 42 watts per channel at 8 ohms. Happened to talk to a Primaluna guy and he told me I needed a more powerful Primaluna amp. That has got to be BS. Do I have bad or weak tubes?? These are KT88's! Maybe they are going out. Who knows. Tried to call Kevin Deal at Upscale but he is out of town. I am not buying a bigger Primaluna amp. Kind of offended that I was even told that. Would the KT120's make a difference? Could it be something else wrong with the amp. Thanks for any help. By the way the amp sounds sweet with small monitors where I don't expect much bass. Thanks for any direction.

Talked to Kevin Deal at Upscale. Really nice guy. We talked for quite some time. He is sending me some new tubes to try first and see if that makes a difference. He knows his stuff. Give him a try. Great customer service.
