I auditioned the Lyr... The Liquid Fire simply destroyed the Lyr hands down. And after changing the tubes on the Liquid Fire to Telefunken CCa's, the LF is a perfect match with the LCD3. Make no mistake, I thought the Lyr was a decent amp - before I listened to the Liquid Fire. If you think the Siemens CCa's sound good on the Lyr, wait till you try a quad on the Liquid Fire.
But, after buying the lcd-3 i can't afford the liquid fire. I hate this hobby.
