Thanks for all of your responses! I'll probably just get the RP-160's (I've been living without a sub for years!) as I can always add a sub later, although that's another issue as my hybrid tube preamp (not an AVR) does have separate balanced pre-outs I could run to a sub, but unless I get say...a Marantz NR1403 AVR or similar to use as a preamp to cut bass to the RP's and run the LFE to the sub I'll probably have some subwoofer integration issues. Also, my tube amps have a fairly bloomy bass, so again, even with an AVR as a preamp, subwoofer integration may prove difficult. Amps are Quicksilver Silver Mono 90. Thanks again, responses have been very helpful. HighDB
