I would be more inclined to say impractical. Many people do things that aren't fiscally reasonable but still find pleasure in them. If you will get that pleasure, then by all means go for it. It's kinda like the guy who buys a classic car from a field for sentimental reasons and plow more than twice the actual dollar value into it and enjoy it as long as they can afford to. I certainly have spent cash I should not have to further my quad gear and others might think I am not too smart for it. If you will get enough pleasure to justify it to yourself and can live with the cost then go for it. If you are in doubt, then hold off and think about it. There are other quad preamps, integrated amps and receivers that came prewired for remotes. JVC and Technics are known for that feature and the remotes are more affordable and plenty if you know where to look. I have a JVC and a Technics remote and both cost under $100US together with shipping. I have an integrated Technics and a JVC receiver (that I prefer to my Sansui) and an integrated Victor (JVC) that take the remotes. A quad preamp can also power modern power amps and be more reliable and replaceable. That said, I tried the remotes and found them more annoying than helpful. Serious noise from old contacts that is intermittent and unpredictable. Difficult to maintain too as parts are not common. I actually find the 6 paces to the audio gear to be easier on my mind and ears. Your experience may be different. One more point I'll add is that most of us who did add remotes to Sansuis did it to the 9001 as it holds the most value and the remote actually can make a small increase in value. The lower units are more common and less valuable for resale. You can put a turbo on a Pinto, but it makes more sense on a Mustang...
