if you're willing to buy used, you might be able to find a pair of gen 2's in your budget. certainly you could find a pair of original duettes for well under your budget. i've got a pair of the original duettes and they are spectacular.
@Udisa, No. Your amp is not up to driving the EA miccroone’s. In fact that amount would only serve speakers that are 90+ efficiency. If you have been using that amp with the Kef 50’s you may not be hearing all that they are capable of. I am using SimAudio Moon i3.3 dpx with my Kef 50's. The amplifier is rated at 3dB for DYNAMIC HEADROOM, which means
that, on musical peaks, it outputs 200 WATTS PER CHANNEL INTO 8-OHMS AND
A WHOPPING 320 WATTS PER CHANNEL INTO 4-OHMS. Inside, this is one of the most beautifully crafted amplifiers I have seen. It is like a work of art. The Kef’s are great speakers as well, but they need robust watts to drive them with authority and aplomb.
@mdp632 thanks! interesting to note, the same pr also writes "The INT-60 builds upon the INT-30A’s legendary “You are there” soundstage, offering spectacular realism, even with difficult speaker loads such as electrostatics or planars"
I think you need to move up,the Pass Labs line and buy more watts per channel. All of your favorite speakers, including the Kef's are not going to sound their best with less than 150 wpc at 8 ohm and 275-300wpc at 4 ohm. Anything less than 90 db efficiency is a tough load and probably has an impedance drop below 4 ohm if it is a two way speaker.
You may want to consider Focal's as well . I drive a pair of 1008Be's with XA100.5 mono blocs with very good results. They are efficient enough where the INT-60 should do fine for most music at reasonable volumes. You may also want to consider the Focal Diablo.
@pops I have not, but very curious about how they would pair with my amp. I don't have any local dealers to demo them. The reviews seem to note these are fairly easy to drive in a small/mid room. What's your experience with them?
Udisa: Size wise M30 not too bad,even own bigger C7 on my small room,mine 10x9 similar to yours. Been driving them with tube at 80w ,enough power! Been own pass labs INT-150 ,yours pass will drive harbeth with easy. Is size matter maybe I've try the P3 ,smaller in harbeth line. You can see my set up on system,mine can only take from angle side cause I can't take from front cause too close about 6'.
Udisa my experience with them has been at 3 separate shows and each time they made a big impression on me. They are on the side of accurate, revealing, and big sound, so your Pass (which is believe is slightly warm) might be a great fit. Amplification I heard behind them was lower powered tubes - I cannot remember the particulars but they were in the room with Devores Orangutan speakers and Leban integrated amps which are highly efficient and low power, respectively. There were no big power amps present.
I would look at Penaudio Cenya Signature. I have heard them with the Pass 30.8 and 60.8 and was stunned how good the combination sounded. Stein Music also mated nicely but at a considerable price increase.
@cellorover That's a great suggestion... i was a little worried that at 86 dB, my amp wont make them sing. Moreover, TBS described it as "Darker overall character". Which is similar to how the pass is characterized. is it going to be too dark?
Udisa, I would call the sound more warm than dark. There was a fullness and richness to the sound. Maybe not the soundstage I like the best, but no real complaints...it would be splitting "thick" hairs. I think with a better preamp (maybe tubes) the sound would be "lighter" and faster. I heard them with the bottom of the line Pass preamp and also played direct from a Resolution Cantata Music Center. There were good points about both set ups. I recently added a CJ ET5 to my system (it took 2+ years to get there) and I am most pleased with the sound. Hence, my suggestion to consider a tube preamp. I also ended up going back to all tubes but kept my Resolution M100 mono blocks versus buying Pass. They could be a good alternative to the Pass amps, depending on the rest of your system.
