Thanks to the 1151’s manageable weight and modest size (compared to the behemoths that have crossed my threshold), it was a snap to put them on a pair of Grand Prix Monza amp stands. Because more weight is concentrated in the front half, I moved them far back on the stands to help even the load. I placed them atop the same Wilson Audio Pedestals I use under my reference amplifiers.
Boulder’s speaker terminals are extremely easy to tighten by hand. I chose the set that best separated the speaker cabling from the 15A power cord. Once everything was hooked up, I flipped the main power switches on the 1151’s rear panels. In short order, the amps settled into standby mode, the white LEDs on the front panel blinking on and off. It took just a push of the front panels’ only button to turn the 1151s on fully. I allotted a full hour for warm-up. Rosencrans thought that 15–20 minutes would be sufficient.
