Strange sounds coming from my speakers.

@cobbone1 - CD transports do fail over time. Do you happen to know if it is a problem with the actual transport mechanism or laser? If so, you might want to ping @georgehifi . He has provided the OEM model part numbers to several forum posters when they needed replacement CD drives/lasers. Of course, you can check with Roksan also. They may have used an inexpensive OEM CD drive/laser assembly that may be relatively inexpensive to replace. It sure would be cool to have a complete working Roksan Caspian stack if the repair were not too expensive.

25 years, eh? That's a pretty good run. BTW, 25 years ago, a Roksan Caspian Integrated amp and Ruark speakers was a pretty darn good system. If it's been well cared for and is still in operational condition, I have no doubt it is still an enjoyable system.

And yes, I've heard things from my system that made me go check the door to see if someone was there, to answer the phone, etc.

Is your 25 year old system still in good condition? Have you ever need a repair in that time? BTW, the capacitors in you integrated amp may be degraded a bit by this time. Usually replacement of the caps is the only maintenance need on an older amp. If you happen to know a competent tech or repair shoppe, you may want to ask them about it. Then again, if everything still sounds fine to you, you may not want to bother.......
