Certainly, the MR-78 is a very fine tuner. It may be the the worlds all time favorite Mac tuner. But IMO and others the CT-7000 is in a class above. Both Stereophile and Absolute Sound ranked it and the Sequerra I (Dick Sequerra designed the Marantz 10) as the two top tuners for several years. Of the two, Both publications preferred the CT-7000. Absolute Sound ranked the MR-78 in their next class down (Class I) but with reservations; citing audible 19-kHz carrier noise. The shop where I bought my CT-7000 (used)had a MR-78 available at the same time--at a considerably higher asking price. I preferred the sound of the Yamaha as did the others present. Another interesting tuner might be Kenwood's KT-917. It was their super tuner of about 20 years ago. Again, quite rare. I cannot comment on its sound as I have only seen them.
