I highly recommend the Thor Audio TPA-30 mono blocks. I use them to drive a pair of Kharma Cermique 1.0's.
Aolrsw, Jtinn and Thorman, thanks for your responses. Aolrsw or Thorman, I've read somewhere that TPA 60 is much better than the 30. Any thoughts? The 60s are probably out of my reach (price-wise), but was just curious. Also, are you getting good enough speed and dynamics from the TPA 30s?
To provide a little bit of background info as to why I started looking for a new amp, when I visited Kyle at Reference Audio Mod, his system (Silver Rock pre and a 60W opamp-based SS amp driving 99dB Montra Sound speakers) with my modded SACD1000 was getting sound that had the you-are-sitting-in-an-orchestra-seat speed and dynamics that I simply could not replicate at home. Since I don't want to part with my Kharmas, I thought I'd look for an amp that has more power than my Aloia (rated at 30W but measured at 60+W).
I am curious if Thor's 30 watts would deliver the awesome dynamics that I am looking for... Maybe it is not even possible to get such sound from the Kharmas? I don't know, but I sure want to find out.
Henry, it might not be your amp. How old are your Kharmas? If they are more than a couple of years old, I suggest looking into a crossover upgrade. I had the crossovers in my 5-year-old Kharma 2's upgraded to "Enigma" by Bill and Anthony at GTT and I WAS COMPLETELY BLOWN AWAY. A veil was lifted from in front of the speakers and I finally heard for real all the "potential" I had sensed in the speaker from day one. Look into it.
Txlef, could you tell me a little more about the upgrade? Did you have to ship your speakers to GTT? What did it cost? Did you upgrade the internal cable or tweeter as well to bring it to the Reference level? Could you provide more info about the change or the difference you heard after the mod? Thanks.
I have not yet upgraded the tweeters. I am waiting to see if Kharma comes out with something new next year. I am fortunate to live only about 45 minutes from GTT's location, and Bill was kind enough to pick up and drop off my speakers for me in his van. I would imagine shipping would cost a couple hundred dollars (too heavy for Brown). All internal wiring and the crossover itself was upgraded to Enigma, and a new bottom plate was installed.
As to the sonic changes, they are amazing. The speaker has greater transparancy, life, speed, rhythm. Bass is tighter. Midrange is smoother and the transition from bottom-end to mids is now essentially flawless to my ears(there used to be some sort of upper bass hump). But the most impressive change is in the upper register, where everything is cleaner, clearer. More extended without any "hi fi" etchiness. Soundstage is broader and deeper. There is an immediacy that was not present before and that rivals anything I have heard anywhere. As I said earlier, it's like a veil was lifted from in front of the speakers.
Call Bill at GTT; I'm sure he will be happy to discuss cost, logistics, etc.
I have a large room ( almost 600 sq feet ) and am having no problem with bass ( though I am not a bass finatic ) with the Thor TPA 30 and Kharma 1.0. I like the balance I have now. There is a thread somewhere in Audiogon that mentioned a nice improvment upgrading to the Thor 60 watt monos.If I were buying my first Thor monos I would probably go for the TPA 60 ,if I could afford it.When I purchased my amp the TPA 60 was not yet available.I am very pleased with the d e Kharma 1.0 and the Thor TPA 30 combination.
You want minimalist? I'm running my Accuphase 75v directly into my Edge NL-10 (AU24), and over to the Sonus Faber EA IIs (Discovery Essential). The sound is detailed, liquid, and surprisingly satisfying in the bass, considering the 6" woofer and modest cabinet.
I do not miss preamp or tubes. In my case, "less is more."
