In 1984, Dire Straits Brothers In Arms became the first album for which cd sales out-did cassette and LP record sales. This milestone is often considered by many to be the start of the end for Cassette Tapes and LP Records. In the later part of the 1980s, CDs were outselling cassettes even in the portable audio market and cassettes were relegated to the developing world markets.
By the time the NAK DR series arrived in the early 1990s, cassettes were considered to be on the verge of being phased out. The DR10 was the last deck from the great Nakamichi stable. Many gurus say that the DR series was compromised by NAK to keep costs down. There are many theories about the DR series being inferior to other earlier NAK models but from my experience, the DR3 is one of the best 2-head decks ever from the NAK stable. It could easily match or outsmart many 3-head cassette decks of those times. However, there were a few NAK models that were very special and ahead of the rest. The 1000 is one of these. Hence the DR series may be good, but it definitely cannot match the 1000. The debate of the 1000 vs the Dragon would be a more on-par one.
