TR vs PR -
The Total Reference was designed to be a full range , state of the art reference speaker that could be driven by any amplification from SETs to big tube and SS, work well in small rooms yet fill a large one, be placement friendly and still sell for a real world price. Judging by the reaction to the speakers by those who purchased them and others who heard them, the above noted goals were largely achieved and this makes the TRs unique.
The TRs were reluctantly discontinued due to factors beyond our control and not due to any inherent shortcomings of the speakers. The were and still are
marvelous speakers.
The Pure Reference was developed with the same design goals as the TR. It was the advent of the incredible high sensitivity Accuton ceramic tweeter and perhaps more importantly the midrange driver, that made the PRs possible. There now existed a single, very sensitive, high resolution driver that could optimally reproduce all the midrange frequencies from 100 hz - 4khz. Couple that with a tweeter designed in identical fashion utilizing the exact cone materials and now we had two drivers capable of breakthrough sonics that could without compromise reproduce all the frequencies from 100 hz - 35 khz.
Add to that the amazing woofers first used in the TR and the end result is a speaker that meets all the design goals of the TR but with the advantages of using fewer drivers(greater coherency, precision and continuousness) with none of the disadvantages(less power handling capability, curtailed dynamics or impact).
Heard on its own, the TR is everything one could ask for in a speaker. Its flaws are negligible yet its strengths overwhelming. As many TR owners have stated, it is difficult to believe anything could be superior. The PR is. It is not dramatic or anything resembling night or day. It is in the subtleties where the differences exist. The PR just sounds " less there"- a little purer and more transparent, more cohesive from top to bottom, a slightly greater sense of seeing into the music with no distractions. Those who have heard or purchased the PRs have been changed by the experience.
