Is D for Dry? Class D...
I have owned a Mac MC275 and a Mac C20. Both refurbished. Nice, transparent and warm... Years later I discovered a NuPrime ST-10. It matched the warmth and transparency in its own way, but controls the bass near perfect. The tubes can not match the accuracy, nor bass control I can not speak for all D amps. |
dougeyjones, Around 1995, I experimented with various mike preamps using a few SS condenser mikes. I made a 1 min recording of my violin part in the opening of the Mendelssohn violin concerto for each combination. I tried to standardize my playing of each take, although of course I can't be sure each take was identical in my playing. The famed B&K 4011 cardioid SS mike was flat in freq response, but it was smooth and rounded like tubes. I tried Shure, Schoeps, AKG small diaphragm cardioid mikes, but my favorite sound was the Neumann KM184 for its brilliance. I didn't even consider any tube mikes or tube mike preamps, because I had long outgrown my brief infatuation with romantic, euphonic tube sound. The industry standard mike preamp was the Millenia Media for accuracy. But the Bryston and John Hardy mike preamps were significantly more revealing. |
There were only a dozen EVS 1200 amps made.....there is nothing to answer. There is one guy who preferred some $7K mono block tube amps on his modded Ulfberht's. Everyone else is happy. What I do know is that the stock IceEdge (Legacy type implementation) is not something I could live with. The mods (by the way, if you want to know more about them......just call me and I will describe every mod in detail to you) change/improve the sound a lot. However, knowing what is possible....there is no way the modded IceEdge is state of the art. There is always more. I don't see any "refined" parts in the Legacy amp. The raising of the input impedance is just one of 13 things I do to the module. Many things I did to the module made more difference than raising the input impedance. stock IceEdge amp review..... http://www.10audio.com/mivera_1200as2.htm A review of the Legacy i-v7 amp (the same as the I-v4 Ultra except all channels hooked up). When he listened in stereo, I believe, he listened to the front channels in mono block mode. Read the review.....he liked it....however, it did not do everything as well as his reference amp. https://hometheaterhifi.com/reviews/amplifier/power-amplifier/legacy-audio-i-v7-multichannel-amplifi... |
Ric specifically states that increasing the input impedance to 150K ohms sounds "way better."That's furphy. That is only true if it's input impedance was <10kohm and when if what's driving it, has a "high'ish >1kohm" output impedance, like tube pre or passive pre. But as said, it had 38kohm input impedance, and just about anything drives that, so it's a furphy. Cheers George |
