Reel to reel deck directly to power 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.

potential turn on thumps. Turn on thumps from the deck in question, might be a problem.

Consider investigating that firstly with a preamp and some headphones.

If no combination of reel deck output levels at turn on of said deck, are capable of producing a thump that might damage speakers (if connected directly to the power amp), then you are good to go.

Not all decks are built equal in this, some have thumps of various levels some are designed to have no thump issues of any kind. They are not meant to be hooked up to any power amp directly, even if this can easily be done. Some companies will build with this thump issue in mind, some will build with minimum to no thump concerns at all, and thus some thump of some sort may occur, based on how the given deck is turned on vs it's output level settings.

It’s always wise to check this before going forward. Only takes a few minutes....
