Indeed a very capable tape deck. I bought mine as a stand-in while I was planning to do a complete overhaul of my Teac X2000R. While the X2000R has some killer specs, the GX630DB seems to have better overall build quality. It is more 1970's like, with all metal front, single directly driven capstan and no unnecessary bells and whistles.

Two speeds, manual reel size selection and simple controls makes this deck a joy to operate. The reel motors are strong and fast and the transport simple and smooth. It is very quiet during operation and the sound is really nice, crisp and deep.

It will align to high output tapes like Maxell XLI, BASF/RTM SM911, LGR 50P, etc. with no problems. It has a tape type selector, which changes the recording level (adjustable) and equalization (not adjustable). While only tape level can be set differently between the two positions, it is still useful since some tapes sound better in position Low Noise and some sounds better in position Wide Range.
I aligned it to perform well with TDK LX, Maxell UDXL/XLI, BASF LPR-35 and similar tapes. At 7½ ips the difference between source and tape is absolutely minimal with either of those tapes.

It is certainly a much cheaper alternative to buying a top of the line Teac or AKAI from the 1980's, while still having comparable performance mechanically and sound-wise.

I bought mine few years ago. I have always wanted one. Excellent sound. Ità‚´s regrettable that reel to reel tapes are not made today and prices go higher. Mine is DB (dolby) version but dolby is not needed. I donà‚´t use it at all.
