Sunfire Signature or Aragon 8008BB to power SL3?


Follow goners, I come to you again for help in choosing an amp for my SL3.

After more than a year of searching and collecting funds, it has come down to two amps: The Sunfire signature and Aragon 8008BB. Before arriving to these final two, I have looked at Rotel 1090, Bryston 4B-ST, Odyssey Extreme monos, and Levinson 333. I am not into whether the sound is warm or bright, but just good sound-stage, transients, and tonal balance - things that my previous Onkyo 504 couldn’t reproduce (It had great specs, though!).

I am more impressed with the 8008BB, but I cannot seem to shake-off the Sunfire signature, even though I have seldom come across people associating the Sunfire with “deep unbelievable sound stage”. On the other hand, I am not sure if there is a significant sonic difference between the 8008BB and 8008ST, besides their differences in the number of components and power supply design. The 8008ST has a more appealing price.

The lack of a place to demo has forced me to rely on my fellow Goners, and I am grateful for that. I am looking forward to your advice, opinions, and suggestions.

Thanks

I had an Onkyo M-504 at one time. Also had an Onkyo M-508. They didn't like anything less than 4 ohms. Very directional sounding. Replaced with a pair of Odyssey Stratos Monoblocks. Night and day difference. Wide and deep soundstage. 3-D holographic image. Very detailed, smooth and musical. Currently running Infinity Kappa 9's with 4 Odyssey Stratos Monoblocks and an active crossover. More of everything.
To get the wide deep soundstage I would get an ARC VT-100.
I'm using a ARC VT-60 on my Martin Logan Quest Z's and have them biwired with great sucess.If u don't have provision for biwire on the SL-3's then you would need to move up to the ARC VT-100.With the tube ARC, its been my experience over the years that they mate perfectly with Martin Logan's.
S.S. Gear makes Martin Logan's to analytical,cold,with lack of soundstage expansion.Your ticket IMO is a ARC AMP.
76doublebass, thanks for you input. If I ever consider a tube, it will be a pre-amp. Those ss amps are my last choices. The Oddysey Extreme is a little bit expensive for me and they aren't better than the 8008BB, according to my research. But Warnerwh got me thinking; what speakers did your innersound drive?
