Modifying the amplifier's speaker outlets

I have an oldie (marantz 2500) with pin connector outlets for the speakers.  Is there a  place I can find a part to change those to spades or bananas?  I was told that the pin connections will be bottleneck to the flow toward the speakers, and I was told that a few times from different individuals.  I don't know what amount of loss they cause, but I may as well modify them if that is possible.

Thanks

There are numerous speaker terminal

replacements you could retrofit onto your Marantz 2500 receiver if you don't mind a possible irreversible modification.  Drill the rivets out which secure the existing terminals, desolder and remove them and find a suitable replacement to solder and secure in place.  Looks like it will be pretty tight but you should be able to find something that works.  If there is a small circuit board attached to the terminals you might have additional wiring to do for adding new terminals.

Banning forum!

Thanks Jackfish but I could not see the images.  Here's what I get:

 

you do not have permission to access this page. This could be due to one of several reasons:

  1. Your user account may not have sufficient privileges to access this page. Are you trying to edit someone else's post, access administrative features or some other privileged system?
  2. If you are trying to post, the administrator may have disabled your account, or it may be awaiting activation.

Do you think you can send me those pictures for the final product?  I will greatly appreciate it.

Ok, I just got an email from them that "I am approved" and I managed to see the works.  This happened barely two minutes after I sent you this.  Impressive timing!  Very good work.  I wonder if I can actually do that myself or if I can dedicate the time for it, but I should have it in mind anyway.  

I guess for the time being I will get cables with spades and adaptors to use with the existing pin outlets.  How does that sound as an idea?  I guess the sound of the music will not be quite as good with those adaptors but anyway...
