Here is a great new amp from Accuphase if you can afford it, that will drive those Theil’s without breaking a sweat. Not as cheap or as high wattage as the JC1’s but just as brutal with it’s ability to drive low impedances.
"Accuphase’s head of engineering, Masaomi Suzuki, introduced the company’s new P-7300 flagship class-A/B stereo power amplifier ($32,000). The amp outputs 125Wpc into 8 ohms. Its versatility extends to outputting 800Wpc into 1 ohm, which means that loudspeakers with challenging, amp-wilting impedance curves should not present insurmountable problems."
