Any 300B Has A Bit Warmer Presentation?

https://forum.audiogon.com/discussions/coincident-frankenstein-mk-2-amps

Hi nightfall, I responded to your other thread regarding your Coincident amps. The above thread which is 12 years old is still relevant today for owners of Coincident Frankenstein amps imo. There is a good discussion regarding which 300 B’s work well with the Franks. Also, some good info on rectifier tubes. Charles1dad and others give valuable insight in this thread. 

As for seeking more warmth, I too felt the same way when I first got my Franks. I had commented to Charles way back when I first got my amps that I wanted more “meat on the bones.” Instead of replacing the stock 300B tubes with a notably warmer 300B, I went with the EML 300B XLS tubes, just like Charles and others in that thread did. The EML is a neutral, very natural sounding tube that allows you to hear differences in cables and source components. It is not hyper detailed as the above AI response might suggest. When I wanted more scale and weight (some might call this warmth), I accomplished my goal with cables, careful vetting of dacs, and improvements to my analog playback system. One of the main attributes of the Frankensteins are their transparency and a warmer tube might compromise this imo. For me, it has been a blast over the years to more easily hear the differences between cables, dacs, cartridges, etc. If it were me, I would stick with the Elrogs, which Charles also loved, and build around them, assuming your Elrogs are newer production and over the QC issues of the past.

i mostly agree with AI based on paying close attention to a wide variety of reviews of 300B's over the years. My experience in regards to warmth with Acme and new production WE is that WE slightly warmer, sweeter than Acme. @nightfall Interesting you bring up quality with WE, I've had two new production (2024) WE's go gassy in the past year, this in amps that have run Psvane Acme and Shuguang Black Bottles without issues, each well over 1,000 hours. Also, build quality of Acme superior, much thicker glass, weightier, pins seem superior quality and internals look more robust. Very disappointed with WE quality, and still unsure whether they'll warranty second bad tube, we shall see. Also owned Audio Note Quest mono blocks for short while, same sound quality ratings as my reference amps.

So, I'm looking for the exact same warmer signature in a new set of 300B's, based on my research at this point I'd pick Takatsuki, but I have concerns about reliability having seen a few failures out in the field. 

Psvane Acme are likely the best value higher end 300B tube out there, I wouldn't go back to mid tier and lesser 300B tubes, a decently resolving system will expose the cheaper stuff as clearly inferior. I'd save my money for the more expensive tier vs short term saving with lesser tubes. 

@thaluza I wasn't aware that Charles had moved on from the EML to newer production Elrog, interesting.

Try the Shuguang Black Treasure Series 300B-Z. . A warmer tone than most of the moderate priced 300b's .

@sns it was the opposite afaik. Elrog to EML. He was having quality issues with Elrog. I recall he was effusive in his praise for the Elrog though, when thety were working.
