Preamp suggestion for Coincedent M300B Frankenstein mk2


I have a Constellation Inspiration Preamp + Stereo Amp for my Mino-D speakers.

I’ve decided to investigate the “tube” sound so I started with the Coincedent 300B Frankenstein MkII amplifier which I planned to attach to my Constellation (SS) preamp.  The 300B will drive my 100db Volti Rival.   

Am I going in the right direction or should I use a different preamp?  If different, any suggestions?  I’m also a confused if choosing a tube preamp with a tube amp may be too much of tube sound?

You won't be disappointed! Going from MkI to MkII with extra upgrade of Amtrans rotary selectors was so worthwhile!

 

DHT pre's really special, natural synergy with SET amps, all the wonderful aspects of these circuits and tubes are holistic with DHT in both pre and amps. My take is why diminish those special aspects with different topology in pre.

Well said, and why I have had this arrangement for 13 years! I’ll admit however that I have no idea how good the Constellation preamplifier sounds with the Coincident Frankensteins. Given Constellation’s esteem reputation, I have to assume it is quite good. I can only attest to the excellence of the Coincident Statement Line stage.

Very interesting, didn't know there was a MkIII version! Israel also changed heater resistor values from .22uf to .33uf in latest versions of Statement. This change made to insure greater reliability, life from the few quality 101D tubes available today. Present production 101D tubes are somewhat fragile, this should help.

 

For those with Statement really only two present production 101D  top notch, those being Psvane WE and Linalai Elite Solid plate, the mesh plate version had some mid range glare in my setup. All other present production 101D not in same league with transparency, resolution. I may try NOS Western Electric at some point, one needs adapter for these, original 101 used four short equal size pins, new 101 longer pins and two larger diameter.

I had given thought 6 or 7 years ago to getting an adapter and trying vintage Western Electric 101Ds. They were/are relatively rare and expensive. I was very happy with the Psvane W.E. Replica 101D and decided to stay put. If you do go that route let me know what you hear.
