After considerable wait for the right price and right timing, finally I was able to acquire a pair of my dream speaker - the Infinity RS1b. I purchased this pair from an audiophile in Seattle (2nd owner) - who purchased it 14 years ago from a Boeing engineer (1st owner). The 1st owner was an audio reviewer (supposedly to be of some renown). He modified the both passive and active crossovers - but the 2nd owner thinks that the mods improved the bass performance significantly. I happened to be in business trip to Seattle this week and took the opportunity to check the speakers and made arrangement for shipping yesterday. I did not want to send the mid-hi towers (with its fragile base) as is - so I took them apart and sent the emims, emits, passive crossovers, bases, and active crossovers by UPS in boxes. Then, I strapped the mid-hi panel to the base towers and wrapped them with many layers of bubble sheet. See attached pictures. It costs a little more but I think it is safer this way. The unit is in excellent condition - the emims are almost like brand new (tight, straight, no waviness at all), but I need to redo the wiring to the emims and emits. Seller suggested that I use Cardas wire - but I am not sure about it. Let me know of any recommendation that you can suggest. Between work and finishing my house, it will take a while before I will be able to complete the setup of this system. The seller laughed at me when I told them that I plan to power them with a pair of Carver tfm-45 (completely refurbished and upgraded by Rolland). He is using VTL 300 - which I am considering to purchase from him if the price is right. Any thought? Will post more pics when it arrives in couple weeks. Recently, after some tweaking here and there, I am happy with the RSIIb powered by a pair of tfm-45, GF DAC-09, and Denon 1520. The base is not at all lacking (with the base crossover setting at 02:00 position) and go low with quite moderate volume only. I can feel it in my body - sitting almost 20ft away. In my opinion, the RSIIb is significantly superior to the RS 2.5, but in sound stage and detail. When I was at the seller's house - I saw quite few high end equipments - including a pair of monoblock for $30K and a pair of Avalon speaker ($15K). It is truly an eye opener to me to understand what a high end audio is. For now, I am satisfied with my Carvers and DAC 09.
