It was clear that some of the benefits of biamping the 7/2100 for my main speakers was realized after a few short listening sessions, especially at extreme volume levels which I don't usually listen at or recommend. The sound emanating from my reference speakers seemed to have a tad more punch and bass impact when comparing biamp configurations verses single amp configurations of the 7/2100. However, the benefits weren't overly dramatic, especially considering how well a single channel of amplification of the 7/2100 drove each speaker in my reference system. In fact, the more I cranked up the volume, the more at home the 7/2100 seemed to be. I felt the sonic merits of the 7/2100 were very close to that of the 5/1500A previously reviewed here, but perhaps subjectively a tad warmer sounding. I also felt the 7/2100 sounded best after a period of warm up of about 30 minutes or so.

I played quite an extensive selection of my CD and SACD collection on the PT-7000 and 7/2100 Sherbourn combo, and never did I find the fidelity lacking. The noise floor was admirably low, the dynamics endless, and the integration seamless. While I would have liked to see some of the previously mentioned bugs worked out of the PT-7000, it never deterred my listening enjoyment from either music or multi channel surround applications. Playing well recorded SACD's from artists such as Patricia Barber and Grover Washington Jr. was a real treat on the Sherbourn combo.

All of the subtle nuances of these recordings that I was familiar with while listening to them on my reference system were well preserved.

Home theater seemed to be the Sherbourn combo forte. Channel separation was excellent. I never heard any bleed over between channel to channel. The panning between channels was about as good as I have heard on past products previously evaluated. It was obvious to me that the PT-7000 and 7/2100 mated well together both sonically and functionally.

Conclusions

The Sherbourn PT-7000 and 7/2100 are quality products that will deliver very satisfying performance for large, upscale, home theater installs that demand high power output capable of achieving almost limitless SPL levels. These products however are not for everyone. Great care must be considered in their handling and set up, especially the 7/2100, and should be done by experienced home theater enthusiasts or professional custom installers. If your home theater needs coincide with high power demand, easy configurability and usability, and overall excellent performance, than the Sherbourn PT-7000 and 7/2100 combo should be on your shopping list as a viable alternative to mega receivers and other entry level separates alternatives.
