After 20 years, in the market for a power amp

@pvnasby 

I recommend you seriously consider an Audio Research REF 75 SE.  They are around $5k used and will likely bring that for years to come if you ever decided you wanted to move on.  It is super easy to maintain with the bias pots accessible from the front panel and only take 6 tubes in total.  I bought a pair of used Wilson Alexia 1 about a year ago and took my REF 75SE with me to compare to the guy's McIntosh MC 462.  We are comparing 450wpc SS to 75wpc tube.  The output without touching the volume on his preamp was basically identical.  The REF 75SE was much more musical and natural sounding...we both preferred it in his system.  It truly is a special amp and I do not think you would be disappointed.

How much more power do you need than a Primaluna amplifier? For $4k you could have PL’s biggest power amplifier in the EVO 400? If you feel the PL preamplifier provides so much goodness why not mate it with a PL amplifier. What am I missing?

buy a slightly used PARASOUND JC5 by John Curl.   fantastic sound, awesome power, awesome driver control, awesome build quality.   many out there for $5k rather than $7500

Sandy Gross the designer of the speakers used a tube amp in his personal system.  They sounded fantastic with tubes.

Sandy is a customer of ours.

The Khartago, while wholly competent, has long since since been bypassed by the rest of my gear. Looking for something with some synergy with the Primaluna.

Budget $5-7k. Been researching feverishly but it is difficult to get an audition

There are class D amplifiers now that are quite a step forward from the typical solid state- combining the speed and detail of solid state with the smoothness and involving character of the best tube amps, that fall within your budget.

I have the Coda No 8 V1 driving B&W 805 D4’s.
I wholly agree with audphile1 description “Coda no.8 is another option. This amp is faster, more articulate than the Pass but still retains natural tone and is clear and relaxed sounding.”
