I have owned this RTR for a couple of years now and I am very pleased with it's performance.
Like so many of the Akai RTR of which I have listened to they last well over the years with little maintenance other than the most basic.
This model gives exceptional quality reproduction at 71/2 ips and is my favourite RTR.
Given also that it has cassette and 8 track tape recording and replay ability, it really is hard to beat if you are into the vintage analogue scene.
Try streaming from another device straight into the 2000DS and prepare to be surprised at how good it sounds - better than from the device you streamed from.
The Akai 2000SD is rare and they don't come up often but try and get a working one!
Would love to get my hands on the Capstan Sleeve and Pinch Wheel accessories that turn this model into a 15 ips machine...

Answering Steve Pepper´s question:
I used to own one of these. The switch to the left of the volume controls is an EQ (Equalization) switch which works only for the reel-to-reel part of the machine. It must be set for both recording and playback to match the mechanical speed of the tape for best results. It has no effect for cassette or 8-track tapes.
As for the speed selection, with the motor switch on LOW and with the thinnest capstan, reel-to-reel speed is set for 1-7/8 ips (Seldom used, unless you want extra long recording time at the least sound quality).
With the intermediate capstan, reel-to-reel speed is set for 3-3/4 IPS.
Moving the motor switch to HIGH changes speed to 7-1/2 IPS,
and with the motor on HIGH and the largest capstan, reel to reel speed is 15 IPS. (Leave EQ switch set at 7-1/2)
Note: For cassette and 8-track, motor must always be set to LOW speed!.
If you want to TRANSFER from a 7-1/2 IPS recorded reel to either cassette or 8-track, you can still do it by using the LOW speed for the motor and the largest capstan.
Hope this helps!

A machine rough, but high quality. It brilliantly blended the three formats of the time, the reel, cassette and 8-track cartridge.
It is also one of the few that I know of (if not the only) working with four recording speeds for open reels 1-7 / 8, 3-3 / 4, 7-1 / 2 and 15 inches per second. Given the technology of the time, the change was witty, an electronic switch that changes the motor speed (low-high) and two sets of capstan roller-pinnch changing the velocity ratio of belt drive. This 2x2-mechanical electronic 4-speed combination were achieved.
On the subject of sound, despite the years, the machine is still of great quality, and 15-inch recordings are spectacular, clear tough little film ... but it's joy.
Regarding the performance of the cassette is of acceptable quality, plays pretty well, but I prefer a recording cassette deck.
Regarding the cartridge, I have not recorded on it that I have blank tapes, but in reproduction (studio recordings) sounds great.
In short ... like collectible is a gem, and despite the years, as the object of HiFi ... is amazing.
