Thiel speakers--can you power them with reciever?

Your receiver might overheat causing the outputs to blow/short ,possibly passing a lot of voltage to the Theil's blowing them out.Power amps that can drive 4 ohm speakers would on my priority list.

A good B&K or higher end Denon may be able to push them. Thiels will kill a cheaper yamaha or similar. Keep in mind that all Thiels are not equal. A pair of 1.5's will be easier to push than an older pair of 2 or 3's.

The Thiels will bring your receiver to its knees and make it cry for its mamma. You need a separate amplifier with sufficient testicular fortitude to drive the Thiels.

My Sony 5-channel amp rated at 140wpc sounds substantially less punchy and flat in comparison to other good 60-100W audiophile grade amps. Power ratings on AV amps and receivers are often over-rated with higher-end units an exception.

Any of the high end receivers rated as THX Ultra or Ultra 2 can handle 4 ohm speakers. I would also strongly suggest a receiver with a large toroidal power supply. At 130 watts, I am going to guess that your receiver is rated as THX Select and does not have a toroidal PS, which can technically handle nominal 4 ohm loads, but probably not with much aplomb.

Even a THX Utlra 2 rated receiver with a toroidal transformer will not drive the Thiels with the same ease as a dedicated 2 channel high current integrated or separate power amp of the same wattage rating. In order to fit all those electronics in the same chassis, corners have to be cut somewhere, not to mention noise introduced by having DACs in the box.
