I would go with Naim all the way and I would
consider myself a tube lover. I have a 300B
integrated amp and a Naim XS integrated amp.
The Naim has won out in every category even
vocals. I am getting the in your room presence
on vocals with Naim.
However, the Niam is not your typical plug and
play. You do need at least 12 feet length of the
Niam Naca5 speaker wire with deltron plugs, which
is inexpensive, but believe me it just sounds right.
I also have the Teddycap mrkiii power suply. Highly
recommended. To get truy holographic imaging I use
Synergistic Research Powercell SE, Hologram A, Hologram D,
Apex ic's and T2. The Naim and Teddycap are powered by Audience
PDC, also highly recommended. Also, recommended are the
Audioprism ground control spades and rca's. They will give
you more width, depth, detail and improved timbre. I hear
the Walker HDL's are also worth the investment.
This combo has given me a remarkable holographic sound stage
with tons of air while giving a musical presentation that sounds like music. The Niam/DeVore combination is the most
emotionally captivating gear I have experience.
Also, since the Silverbacks are very efficient, I doubt that
you would even need Naim separates.
