Alternatives to Rogue Stereo 100

Understood.  PrimaLuna was definitely on my short list.  Along with Cayin, Cary, Quicksilver and Line Magnetic.  I like the idea of American made gear...which probably pointed me to Rogue in the first place.

Thanks.  I thought of that, but from what I've deduced, power tubes add more "tubiness" than just a tube-pre.  I really want to swing the pendulum to the other side of the spectrum.  I've intentionally set up a high powered, revealing system.  Now I want to try the other side of the conversation.  I'm hoping a tube amp would introduce enough of the tube sound to give me a different experience.  audioconnection's comment above is a good one...perhaps I'll need to try out a different speaker to get away from leanness...though I do love my PMCs.

So, lowrider57, you're saying that I need tubes in both pre and power section to get true tubiness, and that putting a Rogue after my Ayre will keep my system fairly neutral...as it is now with a solid state amp?

Thanks, mac48025.  The Raven stuff looks great.  I thought about an integrated...but I've got real money invested in the Ayre, and I'd like to keep it in the chain.  It's great to learn about American companies making solid audio gear at "reasonable" prices.  Unfortunately the power amps at Raven are a bit above my budget right now.  Trying to stay around the $2500 mark.  

Thanks, c_s.  Just so happens a Primaluna Prologue 5 showed up on my local craigslist for $900.  Has me interested...and it's a fair bit cheaper way to try out my first good piece of tube gear.

Got the Primaluna Prologue 5 this week used from Gig Harbor Audio in Washington.  The KT88s have been replaced with KT120s.  It seems a quality piece of kit.  It's quiet and clean, and I'm initially impressed with the quality.  Clearly the base extension does not match my Primare or Aragon solid state gear, but the highs are good.  Although the mids are slightly accentuated, they are definitely pleasant and realistic.  But the most obvious difference is the sound stage, which appears wider than my SS gear and with more separation between the instruments.  I've heard people use the term holographic with tube gear.  Although I'm not sure that's exactly the right word, it does seem to capture the essence of the sound.  More engaging...less flat spatially.  I'm happy with the sound overall, but it is not a night and day difference from the quality SS amps I have.  Also, the power of the amp seems quite adequate with my PMC TB2i speakers.  I don't detect any problems getting adequate volume or any strain in the sound.  It's lovely overall.
