CDP-Tube Suggestions

I am currently trying the Sovtek WA's (12ax7). The LPS's stayed in for a while. I really liked them.

The WA's sound just a little bit more rolled back in the highs. Not much though. Its somewhat hard to put into words, but.....sounds/notes seem to "bloom" with the WA's. The bass isnt as pronounced as some of the other tubes. However, bass notes seem more differentiated. Less "one-note-itis." I like the the way the WA's do vocals. They are going to stay in a while.

I also have a pair of Shuguang tubes I will post my thoughts on these later.

After pulling the Sovteks LPS's and comparing them with the EH's, I realized how faulty my memory can be. Side by side, it is immediately recognizable that these are two different tubes. Though they do sound similar.

I thought I might update this thread. I have been running Telefunken smooth plate 12ax7s for a little while now. These are the best synergistic match for me and my system yet. I love them. Very smooth. Vocals bloom from way back and seeming higher above the plane of tweeters themselve. Detail is present without to much emphasis on the highs. Strings ohhh strings, you can hear the pluck so well its hard to put into words.

I have taken the Vibrapods from underneath the unit and placed them under the Sony, which this unit is stacked upon for now. The DH Labs BL-1s have been replaced with Harmonic Technology Pro-Silway 3s. That in and of itself made a nice improvement.

Just for the record I tried the Telefunkens and liked 'em. So I put back in the EH's and tried them again, just to make sure. Then the Sovtek LPS's went back in and within a few days each I would start missing the Tele's. So far only the Telefunken tubes have this impact on me and my tube swapping.

I am curious. I leave this unit powered on 24/7. how long will the Tele's last? I have Pearl coolers installed. I am thinking 8000 hours?

When you say you leave the unit powered on 24/7, is the on-off button blue or red in color? You can keep the unit in a semi-on condition (red color), which won't provide tube current, but keeps the unit in a standby mode. I think you can only go to standby mode with the remote, but I could be wrong (too lazy to check the manual!).

Anyway, I bring this up in that it may be a reasonable alternative to "Full-on" mode (blue light). The manual may have more information.

Hello Djbnh, Blue light on, straight up power on. Though after giving a little thought to the cost of replacement telefunkens. I have decided to put the unit on standby (red light - with remote) when listening is unlikely.

Nice looking system. I see you have tried the GE blackplates and the Sylvanias. Lucky you. Those are some tough tubes to come by. I am keeping my eye peeled but so far I am quite happy with the teles.

Have you ever tried leaving your Jolida on (blue light) for a few days and then have a listening session? I am curious. Do you hear anything different or am I nuts? Mine seems more tonally smooth, less grain, a lot more depth.
