Help for a Lo-Fi guy

Here ya go!

your description of the amp is correct

this amp has been made over 25-30 years so the value can be somewhat different depending on the age of it

basically it's sale value if in good condition is in the low $2000's, $2500 or more if it is a newer version with a sexy finish

Is there any extra tubes with it iso which ones and brands listed,

and you have to pack them very well and shipping cost today is a extra expense 

sell here on U.S audio mart , PayPal or stripe , if local pickup even better.

Those eBay asks are too high for used gear. The Polish ad is over new price, for a used unit. Forget the HiFi shark. Cary is selling new 300B SEIs direct for $3895.00, so estimate a fair used price accordingly. You didn’t say how old the units are or whether all of the original materials are still with the units, remotes, etc.

Any units that have been serviced, it is beneficial to have the service record, just as you would want with a car.

At this price, buyers will want to listen to them, or have a firm right to return for refund.

If you are offering the owner to buy them as-is, and you know they are working correctly, I might suggest 60-65% new MSRP assuming the cosmetics are excellent, the tubes are not too old and all the accessories are included, and less if there is less than that.

Thank you all that took the time to respond... I think I have an idea of worth from your responses. I may end up with one of them and sell the other one for my friend...Once again thanks all.

I was a Cary dealer years ago and this is a nice unit, however you need efficient speakers for best results. I think a fair price for these is in the $1500.00 - $1700.00 range and maybe have them checked out by a tech to see if everything is ok. They might also benefit from a capacitor upgrade. BTW: Your Yamaha M85 has sold for $600.00 - $880.00 shipped and the C80 sold for $200.00 - $500.00 shipped.

I own a CAD 300SEI. Purchased new 4 years ago for $5K+ with all the options.  You could contact Billy Wright CEO at Cary and provide the serial numbers. He will tell you the age and what options are included billy@caryaudio.com which should allow you to put a price on the units.
 

I love this little unit.  I run it with Western Electric 300Bs into Klipsch Belles, Zu Dirty Weekends and Sennheiser headphones. It’s a keeper!

Ask Kurt at echo audio (echohifi.com) to see what he would give you for them. He does consignments too. He is good to work with

"Yamaha separates (M85 amp,C80 pre amp)"

Give yourself a little more credit.  These are definitely NOT Lo-Fi pieces.

I never pay over 50% for a used piece and that’s if it’s current. Normally pay 30%ish if it’s older. Just because there are guys asking certain prices I assume they are getting 20% less or so depending. 

If these are 30 years old, then 50% NPP or less provided they are in fully operating condition and there is documented recent service for cleaning and recapping. The age of the tubes should be established. If they are old, then a significant discount should be expected. Good 300Bs are pricey, and this is a high-quality amp that should be using comparable-quality tubes. If there is cosmetic damage, discount further accordingly (I find any chassis rust particularly suspicious and would not consider purchasing a unit with rusting, mainly because I would suspect other damage from wet or humidity.)

Amps are sweeties, try to keep them, Use one and keep the other for backup.  I use to know Dennis Hadd. He's a good guy.  I still have and use his Rocket 88.

You need to determine listeing style.  If you like it loud and have a big room, then you need 90db plus speakers.  If you like it soft and have a small room, then you don't need much power. 

And have those tubes checked, especially the big 300s, some last and some don't, thats the way tubes are.
