Hey Dennis - what good start on vinyl you have

Yeah, cartridges need some time to wear in....both the internals (damping bits, coils, etc) and often the stylus point, too. Bass
tends to be soft until it wears/burns in - much as you are experiencing.
A vacuum cleaning machine is a very nice accessory...once the grooves are cleaned, you will find treble sounding much more refined. The low end VPI and Nitty Gritty's are good....KABUSA makes a model EV-1 that is cheap, small and less costly - and does the same as the more costly models - you simply add your own home vacuum suction to make it work for you.
It should be a lot less to ship to Singapore than anything else - assuming you have a canister or good upright (with tools) there to use.

For me, treble is the overriding difference between CD and vinyl....treble is where the excitement in music is, without it you have a dead format. Which, as good as you gussy up CD/redbook, it ends up sounding less appealling.
I hope you find, in time, the same.
