Recommend a good tube power amp in the 100 wpc range for under $4k

Folks, 

 I am looking to bi-amp my Fyne F702 speakers, with a solid state amp for the low end and a tube amp for the mods and highs.  The Fynes are floor standing 2.5 way units with 93 db sensitivity and 100 wpc rms power handling capacity.  My preamp is a Rogue Audio RP-7, and my current solid state power amp is a Benchmark AHB2 at 100 wpc.  My goal is not so much more power but to put a tube amp on the middle and highs.  The Fynes have two sets of binding posts, one for lower frequencies and one for mids and highs.  I am looking to go active bi-amping with a Sublime Acoustic K231 Stereo 3-Way Active Crossover.

  In addition to an amplifier recommendation, what else do I need to consider?  For example, if I buy an amplifier with wattage output similar to the AHB2, what other factors do I need to consider?  Because I do NOT want to modify the speakers in any way, do I need to consider a gain control to match level differences resulting from other factors, such as impedance differences? Or, can I just hook up the crossover between the preamp and the two power amps and enjoy the music, which is what it is really all about anyhow?

 

Many thanks for any and all comments.

Hi Mike;

 

I think this has been well covered here but my 2c worth is that bi-amping is a great way to have imbalance in your sound and your checkbook. "On paper" bi amping seems like it makes sense but in your listening room you are going to have a sonic disaster.

If you are married to the idea of 2 amps use matched mono block tube amp but NOT bi-amping. Tubes are always welcome as they produce wonderful warm sound and a LOT of volume.

Personally I’d go with a good used Audio Research stereo tube amp with under 1500 hours on it. They are built like tanks, sound amazing, are much more affordable than the new ones, and don’t loose value if you choose to trade up. (Of course sound is a preference like blondes vs. brunettes or French wine vs. California wine. Only you can choose what "sounds best") One other thing- ignore anyone who makes fun of what YOU like.

 

I have a great used Audio Research VT130 tube amp for sale for sale 3.5K It was my favorite "large format" amp until I put my hand up on a pair of Ref 250SEs (8K 1900 hrs plus nearly $500 in FedEx freight. Ouch!)

 

Remember the KISS principal- Keep It Simple, Stupid!

Hope this helps!
