We shall be pleased to send you the complete Hirsch-Houck report if you write to us directly. If you'd rather not wait, here are some additional key excerpts:
"...the extremely low flutter, flat frequency response and low noise level of the 819, combined with its superbly accurate and useful meters, make this one of the more attractive values in a high-quality cassette deck. Such features as the fade/edit system and the bi-directional memory can be considered simply as bonuses.
"The Maxell UD-XL-I tape provided a very flat record-playback response (at-20dB) within ±0.75 dB from 30 to 15,000 Hz ...the response with Sony Ferrichrome was flat within ±1 dB from 33 to 15,000 Hz... the Dolby tracking was among the best we have measured ...with a weighted rms reading the flutter was an amazing 0.035 percent. It is clear that in all aspects of its design and performance, the Dual 819 is a first-class unit."
One final comment of our own.
As you know, Dual's reputation for quality, precision and reliability has been based upon the performance of our turntables. When we introduced our first cassette decks, we knew they must establish a reputation of their own. And it is evident that they are doing just that.
