Strange sounds coming from my speakers.

It sounds like you hit on the right combination first time around and got a very resolving system. After many changes and tweaks, I've got to where, with the proper recording, I look around to see if someone is in the room or are startled by what is in the recording, thinking it's coming from an open window or door, only to find it's just what I'm listening to. 

No need for that white van to come around, unless it's some meal you ordered. 

All the best,

@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.

Well done. Even if the amplifier may not have seen that much use, replacing the elektrolytic capacitors could still be a wise precaution, if you can find an affordable maintenance engineer. Personally I would not bother with the cd player. Either you move over to streaming completely, or buy an affordable Bluray player with analogue output. That way you will also have the opportunity to watch movies with decent sound.

Just get the Roksan recapped and serviced as other have suggested.

Happens to me all the time, not just me but guests too. Wasted much energy getting on my feet to check the door or the kitchen, garage etc. I really hate it when I'm jamming and a guest says I think there was a knock on the door or they turn their heads and look behind them.
