Thanks for the kind words. It is much appreciated. From what I have seen, most Wilsons have that almost 2 ohm dip at around 25 hz and 80 hz or 90 hz.... It is not something particular to the W/P 8..... but, Ok, good idea to test with a SS amp.... I do not have any high dollar SS amps, but, I do have an Adcom GFA-585 LE in my home theater that I am currently having refurbished due to cap leakage. I also have a Sony STR-GX9ES receiver in another room - which I think does not qualify... The Adcom GFA-585 is hardly high $$, but, it does put out lots of current - 250 watts at 8 ohm, 400 watts at 4 ohm.. When it is done being fixed, and I am satisfied that it is again working to spec., I will try the 585 on the W/P 8s. Attached below are the specs of the Adcom 585... Do you think it is a good enough amp to make the test between two MC275s tube amps and a decent SS amp on the W/P 8s ?

Some additional quotes I found regarding this Adcom GFA-585LE amp. I am not sure if it is competitive to today’s amp technology.....:
"this is the Crown Jewel of Adcom amplifiers.It is regarded as the best Adcom has ever made. There were only 3000 of these made. This is an extremely powerful amplifier. It puts out a real 250wpc into 8 ohms and 450wpc into 4 ohms. To give you an idea of the power of this amp,you would have to put two 565 Adcom monoblocks in the same chassis to equal it.The 585 will drive any speaker. Not even the 5802 Adcom can go there with this amp.It uses Bipolar technology along with being a dual mono design. The transformer (70,000 uf storage)in this amplifier is at least half the weight of the entire amplifier. For the money this monster's hard to beat. It is perfect for electrostats, or hard to drive speakers, or if you just want a lot of headroom".
