Controls Some typical comments from owners. This amplifier is a first class piece of equipment, even in today’s exacting standards. Like with some other of the old Technics Amps, this one is also underrated. With a very advanced Phono (only MM) Pre Amp and a very nice power amp, this one sounds charming and quite warm… If you are looking for an small office amp this is the right one for you.

The Acoustic Research AR-8B is one of my favorite small speakers from the early 1980’s–I had a pair in my home system for some 8 years, paired with a similar Technics amplifier. The AR are a reasonably heavy yet compact speaker — 14.75″x 9.5″ x6.25 with a 6 inch woofer and 1.25 inch cone tweeter. The very linear phase response contributes to good detail and the crossover/woofer design allows for a natural low bass low roll-off without distortion and audible artifacts (“pseudo-bass”). Given the obvious limitations of its driver diameter and enclosure size, reviewers gave it high grades. Although it is hardly reasonable, we could not resist making an A/B comparison between the AR-8B and our reference speakers, which cost about fifteen times as much. Nevertheless, the small size and low price of the AR-8B make it a very attractive choice for budget-priced systems and installations where space is limited. Flat frequency response, low distortion, and reasonably well dispersed sound in the critical frequency range of 100-10,000 Hz. A very attractive choice for budget priced systems and where space is limited. ” a remarkably good sound reproducer”… Filled the room with a sound that totally belied their size and price. In the 1960’s Acoustic Research and KLH dominated the US hi-fi market. Acoustic Research’s AR-4x remained a popular budget 2 way speaker into the 1970’s. But these post-classic AR deserved better. They were very good inexpensive speakers which earned respect as audio moved into the early 80’s. Their acoustic suspension woofers delivered a very acceptable and well-controlled low end response in a small box. The midrange detail was wonderful, the overall balance very good. And the top end was relatively accurate and pleasing. Sadly after the 1980’s, the Teledyne AR were again dismissed by most audiophiles but since 2015 they have regained a better reputation driven by numerous enthusiastic on-line reviews.
