What is the best Reel To Reel machine ever built?


Everyone who has listened to master tapes or dubs knows about the well balanced sound they provide. But it is also important to have a fine tape recorder or playing machine to enjoy the tapes' qualities in a good system.
Maybe my question was raised once before but the relevance of the topic is now greater as the tapes are back to more and more audiophile friends, especially those who are owning excellent phono chains.

I have seen many big & professional machines being recently offered and sold on e-bay, Audiogon and other platforms and I am discussing within a small group which machine is really the "holy grail" among the R2Rs. So why not here. I am interested in findings.

The old Ampex machines were nice, but the tube electronics were designed to be simple and easy to repair in the field but not audiophile grade. Sound beautiful but limited dynamic range and too much color!

This is not true.

The problem here is that when Ampex made their tube electronics was a good 40-55 years ago! They were amazing when they were new (many Living Stereo LPs were recorded on them) but have gone downhill due to age. If they are properly rebuilt they will take any solid state electronics ever made to task. If not rebuilt properly then I would agree that they can be colored- paper coupling caps perform well, but don't last for decades!

The transport is a different matter. It is arguable that the ATR was indeed the state of the art, but if you really wanted to make things go, find a way to make it work with the 351 tube electronics.
Bifwynne,
you may look for sources at Audio Kharma ( reel to reel ). there are many sources mentioned where you can buy tapes. Master Tape dubs you may get e.g. from the Tape Project or AAA in Germany.

I know some audiophiles in the States, Switzerland, Germany who build up their tape collection right now. It looks to me like a small but exclusive renaissance of the R2R which you may also follow on systems displayed on Audiogon - but a small one!

Thesoundhouse,
why is it a crazy question? If you meet someone asking where to buy the best ever built R2R machine for high quality recording & playback do you think the ones you mentioned will win the race? :-)

interesting question. and one i've personally been trying to answer for 4-5 years. and i don't yet have the answer.

my first deck was a 1/4" ATR-102 completely redone by Jeff Gillman of Precision Motor Works. this deck also came with a 1/2" head stack.

then i acquired a pristene condition 1/4" Studer A-820 that was redone by Fred Thal.

then i added a very clean 1/2" Studer A820.

recently i purchased an Ampex 350 in traveling cases, which is a virgin and super clean, but in need of a thourough going thru, which Dave Dintenfass will be re-doing for me.

and lastly i've acquired a very clean Nagra T which should be in my room next week.

at various times all the above machines have been characterized as the best from one perspective or another.

currently i have one set of custom output electronics, the King Cello. i've also purchased a pair of Ampex 351 Mic pre's, which i'm planning on using with a transformer for the low impedence modern heads....once Dave get's those done. i'd like to add one more set of output electronics.

i've been 'told' that the Studer A-820, A80, and Ampex ATR-102 are the very best transports in terms of tape handling and speed accuracy. heads seem to be a matter of taste; different people view those differently based on a sonic compass.

many tape decks are judged by their native output electronics; which mostly are crap, with a few exceptions. some love the tubes, others not.

which one is best? as a machine and considering build quality; there is the Studer A-820 and then there is everything else.

just one man's opinion.
Mike,
your A820 looks like it is in a very good condition. It is of course the crown of all modern Studer machines with five motors and its build quality is from another world. It is also a very rare type you have. You are very priviliged to work with such a machine. I was told the weak point may be the computerized design. new parts a not easy to get but I do think this counts for all Studers exept of the A810.
Oh yes the Nagras. What about the Sonys and MCIs?
