Recommended for those who are having trouble with the harmonica terminals for speaker cable connections on vintage McIntosh.

You want to connect thick cables "directly," but due to issues such as the connection space of the terminals and the small size of the screws, and contact problems with "cable whiskers,"

Many people are forced to use thinner cables or brass banana terminals.

We have prepared terminals that are just the right size for such harmonica terminals, which are not very user-friendly.

Also, when using commercially available electrical Y-terminals with speaker cables, "sound quality degradation," "dulling of the sound image," and "poor high-mid range clarity" due to the influence of tin plating are often mentioned, both now and in the past.

Even expensive and high-quality premium speaker cables are ruined by tin plating.

Various plating processes exist for speaker-related contact points, such as gold, silver, platinum, and rhodium plating.

It is a well-known fact that each plating has its own characteristics in creating different sound tendencies.

For sound creation without coloration, the original sound, "pure and innocent," "straight," non-plating is the best choice.

Non-plated OFC high-purity oxygen-free copper Y-terminals are hard to find.

For those who use high-purity, high-quality copper wire speaker cables, non-plated terminals made of the same metal are the best.

Please give it a try.
