Good morning gentlemen.'
I am tempted to close this thread completely. This dust up does not belong on Whats Best Forum. To remove all of the posts that are argumentative would only serve to disrupt the thread. So I will leave it open and I a going to insist that verita7 as well as plasmod3 cease and desist from any further posts in this thread. To continue posting in this thread will guaranty both of you an extended vacation from WBF. I hope I made myself loud and clear

It seems to me (correct me if I am wrong) that you are a member of the industry . As part of out Terms of Service we require that all members with an industry affiliation indicate that in their signature which can be accessed in your settings. I strongly urge you to do that now going forward.
And a reminder to both verita7 and plasmod3, you're both done posting in this thread. If there are further eruptions elsewhere on the site between the two of you, your memberships here at WBF will be terminated

In the spirit of Steve's direction, allow me to try to redirect this onto a more positive plane. So for those who are curious, the Koda K15EX has some interesting options I am starting to learn about:
- a ground connection
- a Super Ground internally
- a floating ground switch
- and the ability to flip everything from SE out to true Balanced out only...which as I understand also means (in recording studios) that a lot of cross talk you get from too many RCA cables running around is eliminated.
I am only just now starting to understand what this all means. I am using the grounding connection to the Tripoint Troy. I have flipped to the 'lift' option on the switch because there is a risk of grounding noise in the system, and obviously the Super Ground being internal is just 'there'...no on/off. And I am using balanced out (first time ever for me, as I have been an SE-only CJ preamp owner for 20 consecutive years!)
I will say this...this is the first time I can walk right past the speaker and not know if the system is on or not. That is quite cool...and while I know that is not the same as system noise floor per se (i am sure someone more technical can explain)...it IS nice not to have tube hiss, or humming or buzzing no matter how soft.
Yes, there is the slighest noise if i put my ear on the tweeter, but if there is any ambient noise from outdoors (car, or windy day)...then it is hard to consistently hear this noise.
The measurements published indicated 114db signal to noise.

Change that to EQ and i thought you were talking about a certain world leader...
If you open the case, you will find that the volume control is connected to different resistors. By rotating the volume control, it will choose different resistors. Unless, Robert builds in some motor switch, I don’t think there will be remote control.
Yes. I am not holding my breath...I need to do it Japanese style and have it all on the coffee table in front of me.
I remember our first Akai VCR had a remote control connected by a cord. That was wild at the time.
Wow...clearly a lot's happened since I signed off! As people have kindly said, back to the K15EX!
Regarding a question someone posted overnight about the Super Ground, I did ask one owner who upgraded his K15EX to K15EX Super Ground. He told me the 'quietest preamp' he had used became even quieter. I did not get the sense there was anything that was 'edited' in terms of voicing, or anything else...which makes sense to me. And while I have very little reference never having owned SS preamps (but having used quite a few)...I will say that it is crazy that I can walk by the speakers and not know if the system is on or not...that for me is a weird experience. I am sure many audiophiles here are totally used to that...but for me there is quiet and there is "is it even on?" That translates directly into what happens when you push play...
...relative to the remarkably quiet/detailed CJ GAT 2 which loves nuance and detailed breathe when singers pause, etc...the Koda K15EX gave me violins or guitars very, very, VERY quietly playing a harmonic parallel tune way off in the background which I literally had never heard before...clear as day in the background. I have to say, whether that is K15, K15EX or Superground...I am extraordinarily impressed. It is one thing to get more detail, it is another to hear [very consistently across 50 CDs I have now heard] new lines of information, singing, words, in the far off background I had never heard before, and handled with an extraordinarily deft touch by the K15EX. Effortless.
BTW, for further information, I ALSO spoke with 1-2 owners who UPGRADED their K15 to the K15EX, and I got the clear impression for an extra (20%??) of the original price, it was extraordinarily well worth it. Overall, a dramatic improvement. Particularly in the area of dynamic explosiveness and bass power. It sounds to me that the original K15 (like the CJ GAT/GAT 2) is extraordinarily 'even tempered' when it comes to explosiveness in attack particularly in the bass. By contrast, the K15EX apparently has a greater power, dynamic attack capability in the bass.
And then on top of that it did seem like overall the rest of the spectrum was also improved in terms of bringing music to life...as in 'life like'.
Hope that helps.

Hi Duy. I thought it was you. I bought your Accuphase C-37 a couple of years ago. Still going strong. Would like to hear the new C-47.
Did you ever get your analog set up?
The sound you get in that small room is amazing.
Cheers Shane
