In Reply to: RE: How to “warm-up” the sound of my CD based system? posted by moosejeeves on May 21, 2009 at 10:32:01
If your using the stock tubes. Get some NOS tubes Some nice Amperex 50s early 60s will do the trick or early Siemens E88CC (6922)
also if you are using and pure silver cables, you might want to try copper.

Seimens will do the opposite. Their treble can be very pronounced. Mullards tend to be more laid back and would be a better choice. Amperexes might work, but they can also have a pretty strong treble. Another thing to keep in mind is that there are substantial differences between different years of Amperexes and Siemens. This is a complete science in itself, and you can look into Joe's Tube Lore if you want to get an idea of all of the 6922 variants. If you want an excellent Mullard that will tame the high frequencies look at the list that is linked below and order the "E188CC=7308 Mullard GP". This is a premium variant of the 6922, and they ain't cheap, but experimentation can get very expensive, and lesser tubes (cheaper tubes) usually aren't all that good.
Your points are very good indeed, but my post was more to do with what is more laid back than what I assume is new production crap that is in the OP tube CDP now.
To me a tube with a "good" treble does not mean it can't be laid back. Laid back to me is more of a midrange quality and not being an aggressive sound. Amperex Holland is known as somewhat laid back with many of their tubes with a great midrange. I have many from different years, from D-getters to Dimpled-getters, big O and smaller o getter, to A frame,
My experience spans the whole family of 6DJ8 (ECC88), 6922 (E88CC), 7308 (E188CC), 8329 (E288CC).
Indeed the Siemens are not as laid back as Mullard or Amperex, but they will be a welcomed change in the right direction and not be bright or edgy like what he has now. I find the Siemens 6922 (E88CC) to be very neutral, a very open tube with more air and bigger soundstage then any of the other brands I have tried.
My Favourite of the 6DJ8 family is the early E288CC Siemens with the gray riser support, the Siemens E88CC with the gray riser (some call plates) comes next. I should say that it may not be safe to use the E288CC in most gear as it has a much higher heater current and can cook your transformer.
I agree different years can make a big difference and is why I suggest late 50s and early 60s, there are some other beyond these years that are very good as well, but the early ones stand out in general and each can have some different qualities .
I generally really, really like Mullard tubes but I find of the 6DJ8 family, they can be a bit to laid back, smoothed over for my taste.
Of Course this can be system dependent and a change of one component for another can make the need for a little tube rolling and the Mullards fitting the bill just right.
This is my reason for me selling some of my tubes, but always keeping 1 pair of anything I sell.
No doubt that the Siemens is a better tube than a Sovtek. Its got clarity and soundstage and the Sovteks don't have squat. I also stick to tubes from the sixties. When I got some Amperex and Siemens 6DJ8s from the late seventies, they really sounded poor. Comparing good tubes, I would say that Mullard-> Amperex-> Siemens form a continuum starting with rolled off and ending with a purity that can be too much with the wrong component. However, I have paired a Siemens 6922 with a Koetsu cartridge and it sounded terrific. I also paired a Mullard E188CC with a Dynavector, and the combination is great. But pairing the Dynavector with the Siemens would have been disastrous, as would pairing the Koetsu with the Mullard. In my system, the tonality of Telefunkens seems to work best and I use them in my preamp. I would place them between Mullard and Amperex for treble strength, but they have become very rare and expensive, so I don't think that they make a very good recommendation any more.
Thanks for sharing your experience with Telefunken tubes.
That's one that I don't have alot of experience with, as you say they have priced them selves out. Nice to hear your thoughts on them.
