How good are the AES Sixpacs???

I've owned them for more than a year. Are they better than your current amp, don't know, you would have to be the judge of that. I have owned Krell and Pass Labs SS amps as well as a very good Manley Stingray integrated and I still have the Sixpacs. It really depends on the rest of your system, your musical tastes and what's important to you with regard to sound qualities you are looking for. I can say the build quality is very good, the boxing/packaging is good and they are backed up by a very reputable company in Cary. You can go here to read a little about them. If these are what you're looking for you'll know it when you A/B them against your Primaluna. Bottom line, I like the clarity, weight and smoothness they bring to my system. Good luck!

Some people have said that the Six Packs are better than the Cary V12i (they share similar designs as AES is sort of the lab for future Cary products). I owned the V12i and prior to purchasing it thought hard about getting the Six Packs. I just got a better deal on the V12i so I went with that.

If they are indeed better, or even if they equal the V12i, you'll be pretty happy with the sound. Especially if you pop in some NOS EL-34 tubes. If you can swing it, get the oil cap upgrade and have the plastic speaker posts swapped for gold plated ones.

I just hit my 2-year anniversary with the Sixpacs, and I'm still lovin' them. I have the AES AE-3 DJH pre-amp, too. I couldn't be happier with the combination. If it will best your PrimaLuna...no idea.
