The drivers are the same, the cross overs are slightly different from what i understand. I would bet that the ti's will go quite well with the 160, like i said, i have the 180 and it blends pretty much perfectly with my ti's... All 3 speakers sound the same to me.

I am on the list for a pair of LFR's... With the LFR's you will need more channels of amplification.. you need 4 matched channels of amplification all channels need to have the same gain, this will require the use of outboard amps.

I think that there were 3 "upgrades" between the ti's and the V3's..

If i were in your position, i would offer somewhere between 400-600$, can you go inspect and listen to the speakers? Depending on your relationship with him, you may be able to get him to bring them to your house so you can listen to them with your 160 prior to buying them?
