Audio Research REF 3 worth buying today?


I would like to know your opinion ... it is worth buying a REF 3 today?
He's about 15 years old, it will be necessary to do a recap in the near future?
Thanks in advance for your comments.
Regards!

OH , perhaps also interesting , I retubed also my ARC PH5 by NOS Telefunken E88CC and disconnected the rectifier section for an outboard Border patrol tube rectifier. For me if makes  no sense to upgrade to newer ARC products .
The Audio Research Ref 3 is without a doubt one of the best Preamps I have heard in my 40 years in audio.By it.
I owned the Ref 3 for 6 years.  It has a low noise floor, tight bass and even response.  Lacks enthusiasm, dynamics and speed for rock.  Good at intimate/small venue.  
Following your advice I found a REF 3 in the Netherlands and practically all that remains is to make the payment. I'm waiting to know what the shipping cost is.
Thank you all for your opinions.
