So no one has heard the S7 with the C-core transformer and upgraded caps yet, is that right?
 
Also, is it reasonable to think that the 6SN7 as an output tube in a well-executed circuit (as the S7 no doubt is) is capable of producing images with the palpability of the 2A3?

 
The S7 is very precise in terms of localizing instruments left to right. But if you are referring to the openness, depth, layering, and special characteristics of the direct heated triodes such as the 2A3, the answer is likely no.

I don't think those impressions are in this thread. Could you point me to them, please? Also, we do mean the same thing by palpable imaging and I'm very glad to hear that the S7 can accomplish it.

C-core w/ cap upgrade impressions.Both of us were literally transformer rolling with the same source and headphones.

Yeah, there were cap impressions somewhere earlier from the Bay area meet time frame as well.  No reason not to get it really unless clarity is a bad thing.

Thanks very much. It sounds like the gap between the S7 and BA or 2A3 may have narrowed further. That's also good news.

Today I received my Super 7, however I won't able to give you guys any impressions any time soon due to missing power cords and tubes.  But here are some photos to show you guys.

Congratulation!
 
re: power cord - I am guessing any IEC power cord would be ok.

Nice! Mine should get here this week as well (w/ tubes).

Just want to chime in with some initial impressions with this amp, so far only has about 6hrs of usage so might not be at its best.
 
Setup:
PC USB > HRT Music Streamer II+ > EC Super 7 w/Tung-sol 6SN7 GTB tubes > Sennheiser HD650 w/4pin XLR balanced cable
 
One of the most noticeable sound signature of the S7 is string instruments are very good, it has a nice weight to it.
Bass is another characteristics of this amp very good control of bass slam doesn't feels distort.
I think it is a faster dynamic amp than my Audio-gd ROC amp (SS).
S7 also tame some of the treble spike in my recording, so I able to enjoy my music longer.
Overall, I would say S7 is fast, great bass, smooth and has good instrument body weight amp.
 
I still think either the tube or my source isn't giving me the best of the amp, so I will update in the future if I acquired any new DAC.
 
Thanks for reading.

Cheapest immediately upgrade for ~$30 on eBay taking into account your headphones. Change just the driver tube to a Sylvania chrome top 6SN7GTB.

Something like this purrin? Just that sometimes they have different color text so not sure which is a better match for my setup.

Just PM'd you. Don't want to reveal the true secrets out in the open.

 

[discretesound]

Just received the amp today. Is it normal for the amp to buzz?

 

[prtuc2]

Mine is very quiet, did you check the tubes to see if they are working properly?

 

[SleepyOne]

discretesound - do you mean the transformer hums?
