don't forget the law of "deminishing marginal return to scale"  
__________________________________________________  
 
I'm no student of economy but it seems that the law of diminishing return and return to scale are 2 quite different concepts. ???

Ignore the Mundorf, your V-Cap Telfon is still the best !! It also appears on King's 27D.

I have been working the whole morning trying to equate the new volume setting with that of the old. Owing to the more graceful behavior of the tubes probably, I have found myself constantly turning up the volume more than I should...........  
-----------  
good news! at least it works the whole morning.  
 
you just have to get used to the new volume setting. if you can determine the average number of steps that you want to increase, i can probably simulate the reading of the volume as per the new setting.  
the difference in gain between X0.2 and 27D does not affect the volume setting. it will only affect the maximum setting that can be set on the 27D. the 6 db difference will mean that the 27D maximum setting will always be 6 steps lower than the X0.2 assuming a 1 db step.

Gain of the Pass X0.2 is 12 db against 6 db of the 27D, and the maximum output of the Pass is only 7 volts on the unbalanced rail, not much of a difference I guess.

Of course buy the 27D Lite NOW!!! Still you probably would have changed your DAC 5 times before you would have the 27D Lite delivered. :-)  
-----------  
cp, your prediction is usually correct but in the case of 27D, i've upset your track record. if you doubt it, go to sai kung to find out.  
for the 27D lite, the only thing that is missing is the Aura Teflon cap. it looks like the US is having a long holiday and no one answers email.

There is nothing like good live music.  
 
The best an audio system can do is to simulate live music and therefore it can only be second best. I am just honest, Vash.

Dear sir, why it is the "second best live performance" ? Curious to know which setup is the ultimate and no.1 best live performance in your den ?

27D Lite version 約要多少銀兩?有冇遙控?  
---------------  
it is cheaper than the 27D^-^.  
we are still finalising the bill of material. should be on the website soon.  
 
27D lite is just like the 27D, it can only be operated with a remote control. there are no switches. in fact you can' tell the difference between 27D lite and 27D from the outer appearance except the visual display on the 27D is a large VFD while the 27D lite uses a smaller OLED display.

cp, given your reputation do you think you will ever be missed in the list! anyway i agree with you. i think it is not appropriate for any manufacturer to litter this forum with unsolicited adverts. so dear moderator, pls delete any posts that you think are not appropriate.

The final production 27D performed flawlessly last night.  
The sound was so good and live like that gingers was seen glued to the stereo seat scrambling his Tong Li collection one after another with awe struck silence, quite paralyzed in audio frenzy.

The 27M is already very good sounding.. Life is simple and full of joy, when no comparison is made!  
 
Audiophiles - why always compare for sadness (instead of more joy!) ???

Very good suggestion. But I think readers here (except perhaps a few) know what is a genuine airing out of feeling from untold advertisment. Those who don't know how to distinguish will not be able to appreciate the 27D anyway.

Frankly it was the first time I truly appreciated the advantage of the software controlled volume profile, which could be tailored to every different requirement any user might possibly imagine. The volume setting, when fine tuned, is now approximating the one I have grown accustomed to with the Pass X0.2, except now it is far more refined.  
 
It would certainly take me some more time to squeeze every drop of nectar out of this masterpiece pre-amplifier. Friends here please prepare yourself for a revealing experience of the second best live performance at my den by the end of this month............  
 
Stay tuned.
