Elrog 300B vs Takatsuki 300B tubes


Has anyone heard the Elrog 300B tubes ? I read an article which mentioned that the Elrog 300B delivers 15% less power than a traditional 300B tubes. Can anyone confirm that it is audible ?

I am choosing between Elrog and Takatsuki 300B tubes. I would prefer the Elrog because it is cheaper and supposedly wonderful but if it really sounds less powerful then I have to rethink.

Only thing I want to point out is that the PS Audio units have linear power supplies which is great. I have a NO (or at least very limited) SMPS acceptance policy. I can ALWAYS hear them doing bad things to other gear. Some are much less offensive when well designed but overall I will take a linear supply over a noisy high speed switching supply any day. I have even compared class D amps with SMPS's vs class D with Linear and you guessed it, the class D amp with the Linear supply was far superior.

Perform the following test: While listening to a really well recorded piece of music, plug something in with a SMPS near your audio gear. Most likely the sound will take on a harder colder non-musical signature. The further the outlet powering the device with the SMPS the better. I have experienced this countless times with few exceptions. The Berning Resonant supplies are very very good, the iFi power supplies are much better than most but most others are horrendous. I literally unplug my PS3 (which is not part of my stereo but rather is used as a blue ray player) because it completely destroys my sound (even when it is off). I would never ever buy an expensive piece of audio gear with a SMPS (Resonant Power Supplies are a different animal) unless I could try it in my system with a full money back guarantee.

Wierd example of chopping-power (power supplies) messing up the sound: several years ago I had the excellent sounding Diverter HR in conjunction with my former MSB Power Dac and Meitner Bidat Plus. Everthing sounded wonderful but then one eve while listening I noticed the magic was gone. I went through everything in the chain and found no problem. Through the process of elimination only one change came to mind. I had decreased the brightness of the display on the Diverter. I can hear the scoffers already but the moment I took it back up to full brightness my system was singing again. I talked to Josh the brilliant designer of that awesome piece of gear and he mentioned that the way he reduced the brightness was to employ switching principals.

Just sharing my experiences with someone who may find them beneficial.
I am in no way affiliated with PS Audio but I am truely impressed with the P-10 power regenerator in my system. It does not lower dynamics, shows you incoming power numbers, power regenerated to your system numbers, total harmonic distortion removed and percentage of the capacity of the machine your system is using as well as a surge protector. Linear power supply. I've A/B'd straight to the wall and the PS unit seems to win. I think that when you have tubes that run this close to the top, this machine or one like it is necessary.
I have read this thread with some interest as one of my amps is a Reimyo PAT 777 (best 300B amp I have ever heard) which I have tubed with the awesome and incredibly rare AVVT C37 300BSL (I have a spare pair) tubes. I wonder if anyone has any real world experience as to how the Elrogs or the Takatsuki compare to this tube.

If I have to purchase to compare I will but I'd like to gain any useful insights before tasking my bank account :)
Audiofun,

The Reimyo PAT 777 is an incredible amplifier. I currently own Takatsuki and Elrog 300B tubes and in the past owned the AVVT tube, so I can not offer you a direct comparison. I am planning a long term comparison between the Takatsuki and the Elrog in my Coincident Frankensteins but am holding off doing so until my power issues are sorted out.

Although I have never heard the Reimyo in my system, on those occasions when I had the opportunity to hear it in a familiar system, it was always with NOS Western Electric 300B tubes. I recall that the Reimyo was designed around the WE 300B.

A comparison between NOS WE, Elrog, Takatsuki and the AVVT sounds like an enjoyable way to spend a few weeks.
