Phase Linear DRS250 & DRS900 Review (The Sensible Sound Spring 1984 Number 21)

Here is perhaps one of the last reviews done on any Phase Linear audio components while the company was still in business in 1984. Albeit this was at a time when Jensen had ownership of Phase Linear.

Just some memorable quotes from the above British reference to the PL700:
"It is in fact a precise instrument - and really too good for hi-fi applications."
"The (test results) can only be described as explosive. Ten feet away, the average sound pressure level exceeded 108 db, with peaks over 116 db. The level was literally deafening, and in fact our ears were unable to evaluate the quality of reproduction. Only by using ear plugs could any degree of pleasure be obtained."
"Even with very low efficiency speakers, the sound levels that could be obtained were awe inspiring. Remember that peaks of 116 db correspond to 100 times the sound level of a full symphony orchestra with all members playing flat out."
"If the Phase Linear sales people are serious we must only assume that as far as amplifiers are concerned, some Americans have gone totally power mad; and this device is the latest manifestation of their mania."
"The best way to describe the Phase Linear 700 amplifier is that it is a precision instrument capable of many scientific and industrial uses, but promoted and priced so that a deaf audiophile with a pair of Bose speakers would consider it a bargain."

Love the British.

I just received a reply this morning to a message I sent to Mr. Stravitz 2 years ago. Mr. Stravitz is a friend of Ed Hart's. He stated that Mr. Hart is currently in hospice care. Ed would be approximately 88 or 89 years old now. I only wish I had been contacted sooner so that I could have talked to Mr Hart about some Phase Linear history.
