Congratulations on your much improved sound performance! A high quality active preamp again demonstrating their value in obtaining improved enjoyment, music reproduction and emotional connection.IMO they are essential. Charles, |
Thanks. You need fork, knife and spoon to enjoy the meal. For a long time I used only knife and spoon. Phono preamp direct to amps. No preamp. So I am happy with this investment, and the somewhat muscular effect of the Einstein, being "half-blood" solid-state (in the power supplies), is interesting and perhaps quite a good thing in my context. Although the Callisto or MP-1 might give an even more refined sonic picture. |
So far, the verdict has been in the direction of Callisto, but I like the OTL sound (or lack of it) so I am open to the MP-1 also. For now, for a lower price, the Einstein serves me well, also in the sense that I hear more of my phono and amp upgrades. The grip on the speakers is excellent. Perhaps a bit too muscular, not as refined as some preamps, can't judge, but a big step up for me. Budget did not allow the others (or, ideally, comparing all three). Albert, you are right that I am drawn to the Io Eclipse sound, all the more so since I changed from a worn Lyra Titan to a new Atlas nine months ago. This really sounds excellent. For some reason (German engineering?), with the new preamp, I have especially loved the sound with new elektro music like the "Vermont" LP. BTW I thought that a one-box solution would give less heat, but that is not the case, The Tube runs very hot, perhaps the equal to a Callisto with one power supply. I had the IO Eclipse here and ran it paired with Einstein The Tube, Ypsilon PST 100 preamp, The Messenger, an Allnic L-3000 (original small transformer) model and Aesthetix Callisto Eclipse. The part you need to know is the Einstein gets a massive upgrade when you remove the 12AU7 tubes and replace with 5814 CBS Hytron. I don't think you can prepare for what that does to the Einstein, you might be happy for a long time. This takes away a bit of the electronic but preserves the dynamics and resolution. It's different than what the others I mention bring to the balance but all are very good quality pieces. |
Thanks, Albert, for interesting advice, which I will follow. You probably mean the one 12AU7 tube (only one in The Tube mk2). Do you remember the type of 5814 CBS Hytron? There are some at Ebay, some with orange and some with blue letters. Some are called "CBS Hytron 5814 A Black Plates D-Getter". These may be the same tube, not sure. |
@ Albertporter, Hi, Will the 5814 CBS Hytron tube go in the place of any 12AU7 tube socket that is used in other name brands of componets, never heard of this tube, where is it made, and by who, what is the projected life span, where do you get them from, Is there a specific year that is very good? |
