Heymann: I think DVD-Audio will win the day. Super Audio CD is too expensive, and it's a one-format standard. In a little while, DVD players will play DVD-Video, DVD-Audio, and CDs. These multi-format players will not play Super Audio CDs.

We are prepared. We have been recording for the past three years in six-channel surround, which we can adapt to five-channel surround. I am very keen on the long playing times of DVD-Audio in 16-bit/44kHz, because then we could put the Haydn string quartets on 4 DVDs, saving dealers and customers a lot of…

But yes, I am thinking about it: How do we ensure the survival of what we've built? We've sort of revolutionized the industry. I would never sell to a major. I don't want investors who say I can't do what I want to do—can't record this or that because we have to make a profit every quarter.

I'm not an idealist, mind you. But I am…

Telemann: Born four years before J.S. Bach, Georg Philipp Telemann (1681-1767) outlived him by 17 years. When Telemann died in 1767, age 86, Haydn was 35 and Mozart was 11. And Klaus Heymann is right: Telemann must have written day and night. Music de Table, Tafelmusik, Table Music—whatever. This is great music—the ultimate dining and baroque musical experience, in (so far) four volumes, performed by the Orchestra of the Golden Age. More than four hours of delicious light baroque dining music. If you have a changer, load all four CDs (8.…

Although Rotel is indeed best known for products like entry-level integrated amplifiers, CD players, and modest-output power amplifiers, building a high-power amplifier is not as much of a stretch for them as it might seem. Back in 1996, in Stereophile Guide to Home Theater, I reviewed their RB-985 home-theater amplifier, which…

After running for one hour at 1/3 power, the Rotel RB-1090's case was quite hot, but not abnormally so. DC offset measured 1.8mV in the left channel, 1.1mV in the right. The amplifier is noninverting, with pin 2 positive in its balanced mode. Voltage gain into 8 ohms measured 28.8dB (22dB balanced). Unless noted otherwise, all measurements were taken with the amplifier running in unbalanced mode.

The RB-1090's input impedance measured 33.2k ohms (47.9k ohms balanced). The maximum measured output impedance was 0.16 ohms, at 20kHz into a 4 ohm load, this…
