Tube Preamp Paired with Tube Phono Stage?


Hello everyone. I wanted to know if you paired a tube preamp with a tube phono stage, would that be overkill with respect to the warm sound qualities produced by the equipment? I have a PrimaLuna Prologue Three with all NOS tubes, Clearaudio Smartphono, and CODA Technologies 10.5r SS amplifier. My turntable is the Pro-Ject Debut III with Ortofon OM40. I was considering upgrading to the Clearaudio Basic+ with battery pack OR checking out the new Manley Chinook. But, with two tube units combined, would that be problematic? Thanks for your input.

To run a complete tube fronted is no problem, it depends on the quality (as
usual). There are differences.
Cartridge loading discussions were endless, are endless and will be endless...
To make it short, to dampen a cartridge means, you reduce their headroom,
47kΩ is 'open', you can hear the cart purest, the way it was made, when
your System is not up to the task to handle that (and most can't), you can
dampen it down (some say it has to be done based on high frequency
distortions but that is wrong). With one of the better Phono Stages you can hear
it easily when you step down from 47kΩ it always becomes more slow
and dull (but honestly a lot of Systems need that, the wonder word is:
Compensation, with Cables you can do the same)
To design a Phonostage which is silent, not sensitive to hum or other
influences, probably with higher gain (62dB and more) AND finally has to sound
like music and not dead and lifeless (most do) ---> this is VERY difficult to do ,
the Designer really needs knowledge about that chapter. In the last 15 years I
only heard 3 Phonostages which were able to solve that
- Klyne Phono 7
- Atma-Sphere
- J. Curl Vendetta
All the other countless designers will find endless reasons why their units run
best with 100Ω or 125Ω or 165,37Ω or 358.5Ω -:) but at
the end of the day, they can't do it better. It is the way it is.
Marketing can replace knowledge [and does of course and when it is repeated
countless times, it becomes ---> A Fact :-)]
Years ago a lot of cartridge manufacturers wrote in their datas: recommended
loading 47kOhm (Benz for example)....with the result, that the customers
tortured their dealers that their Phonostages were not able to run with
47kΩ (or they sounded simply awful with this setting, Levinson, XONO and
so on), and they didn't buy the cartridge.
No deal is the worst deal for a 'Dealer'
Now we have in the manuals: Recommended loading 100Ω -47kΩ
The problem is solved now.
That's High End :-)
