I have owned both the 140's and Model 1 Sigs, with different integrateds- Musical Fidelity a3.2 and a308, Simaudio I-3SE and Plinius 8200 mkii. The MF a3.2 seemed a bit weak. The MF a308 had plenty of power but lacking in detail and soundstage. The Sim I-3SE was very musical and detailed, but could use a bit more uumph. The Plinius 8200 mkii, though just a bit bloated sounding to my ears, was the best match.
I would respectfully disagree with Hieule5 in his statement that these speakers are "worth matching with amplifiers that cost as much as three times the amount that you invest into the Totem Model One or the Dyn 52 se". The cost would be in the $6000.00 area. Great sound? Absolutely. A good amp/ speaker cost ratio? My thinking is the money could be better spent elsewhere in your system or in music.
