Pshaw. I've been using a KR-40 for 23 years now and learned to love those
little clicks. The snappy feel of the magnetic springs and positive
response from the relay enhance my sense of timming. Now for a super quite
relay, check the Allied or Newark catalogs for a Mercury Wetted Reed
Relay (try saying that 3 times real fast). These relays are amost totally
silent, fast and can handle much more current than the dry reed relays.
The down side is expense, about $16 and the fact that they must be kept
with about 30 degrees of vertical.
