new hammers

[Dave Nereson]

To those of you who replace a lot of hammers:
    What are the densest hammers "out there" now, i.e., which brand is most
likely to brighten up or increase power and/or volume?
    I've used Abel once and Ronsen once, and was pleased, but this time need
brightness.  What's the difference between Renner and Renner "Blues"?   Are
the "Hamburg Steinway" hammers in the APSCO catalog actually Steinway?  I
thought Hamburg Steinway used Renner hammers (?).
    Have also used Imadegawa once, a long time ago, and they were fairly
dense, but don't know what they're like nowdays.
    Thanks for any info.  Sincerely, David Nereson, RPT, Denver
