Reel to reel deck directly to power amp ?

Ralph hasn’t responded yet about the dbm question I raised, so I did some further research and it appears that what I said was correct. dbm in this context represents decibels above 1 milliwatt into 600 ohms. So the voltage numbers I calculated were correct.

It also happens that the 0.775 volt maximum output of the Technics deck that was referred to corresponds to 0 dbm, since 0.775 volts into 600 ohms corresponds to 1 milliwatt.

So the bottom line is that with some combinations of tape decks and power amps it will be possible for the power amp to be driven to full power, and with some combinations it will not be possible. Generally speaking a problem is likeliest to arise in cases in which the amp is high powered (and most or all of its power capability is actually required by the user, at least occasionally), since there tends to be a **loose** correlation between the power capability of various amplifiers and the input voltages required to drive them to full power. Although there are many exceptions to that, of course, where a higher powered amp may require less input voltage to be driven to full power than a lower powered amp.

Ralph will probably respond tomorrow.
Right now it appears that all this would require a careful match, which is not bad but can be complicated. Would you spend $5k more on deck or on power amp ? Studer A810 is at least that much more expensive. But it should be more versatile in terms of match
They are both toys compared to this, I guess.

Inna, I said it once, and I'll say it again; unless you have a source for good "blank" tape at a reasonable cost, forget about a reel to reel, and if you have a source, please inform me.

Tape

One has always been able to get blank tape for $50 dollars a reel. Two reels are needed at 15 IPS to drop down an album. This is about passion for involvement with the medium. And if one thinks playing vinyl is alot of work ...try playing albums on 15 IPS tapes for 8 hours.
