I've had my Transcription now about 10 days. I wanted to try to get at least a little break-in before posting about it. But I also had a bit of a concern at first - while the sound was good, there was more noise than I felt was acceptable. I did not use the stock tubes at all - I've tried the tubes that EC includes, and have not been impressed. So I first put in a Mullard CV1988 and a pair of Sylvania gray-plate 12AX7's. I'm using it in MC mode, so I know better than to expect total silence, but still this did result in much more tube-rush type noise than I was happy with.
So I let that go while I broke the amp in a while, and the changed to a Sylvania 6SN7WGT and a pair of Tung-Sol military 12AX7WA's from 1963. MUCH better. Since the noise had been on both channels, I'm assuming the Mullard was the culprit, but it could have been the Sylvania 12AX7's I guess. In any case, all is well now.
The Transcription is more detailed and has a better soundstage than my Audio Electronics PH1-DJH. It also is a little more forward sounding, and a little less mellow. That means it's closer to neutral - the AE is a little lush. But I wouldn't describe the Transcription as bright. More like "vivid". It sounds very good, actually. I'm pretty happy so far. I definitely like it better than either the AE, or the Ray Samuels Nighthawk, which are the only two phono preamps I have on hand.
