I was refering to the all tube design which put out 18watts.I think that hybrids may do the job depending on wattage,although it would seem like you are trying to get a flavour from both of the worlds,while not achieving the true benefit of a pure design.I could be wrong,since I have never heard the hybrids.I do know that the Karan that replaced the Lamns has a damping factor of 10,000 and the 12inch and 15inch woofers have no choice but to comply with the will of the amp.The change to the system was truly amazing when we switched out the amps.cheers dennis
