Hi, I also own the Cornwall II's, and can definitely state that they are not the problem. Tube amps work wonderfully with them, even the flea-wattage ones. I would suggest that the brightness you don't like is probably coming from the Rogue amp - the Rogue amps are perhaps the brightest tube amps I have ever heard. This is partly because they are relatively high in wattage. I use a PrimaLuna amp, which is about half the wattage of alot of the Rogue stuff, and it has a much warmer sound. I would suggest that you try a lower-wattage amp than the Rogue, and you will probably find the sound you are looking for.
Tube Amp Noise with Klipsch Cornwall II
I just bought a pair of Klipsch Cornwall IIs for my Rogue Cronus integrate amp to replace a pair Spendor S3/5 SEs. Wow - bigger speakers are amazing. BUT now there is hiss coming through both speakers which can be heard 10 feet away - at all settings, even with volume all the way down.
The tube set is:
4 KT77s - which Rogue had made
3 - Electro Harmonix 12AU7s
2 Sovtek 12AX7LPS
Can anyone suggest how to lower my amp noise floor so I can enjoy these speakers?
