Track song 1 sounds more natural "tube" sound on my medium priced computer speaker. More open. And #2 sounds more flat. So number 1 is better with my ears.
I fully agree, and it is astonishing to see so many being of the opposite opinion...! Like the "the white and gold, or blue and black dress" on TH-cam a few years ago
@@and1424 Thx! That confirms my impression and experience. Have during this year owned and sold no less then three different PP tube amps in price range 600$-2500$, and none could compete with the cheap 250$ Single Ended Class A Reisong A10 regarding life-like three dimensional sound presentation.
#1 has more spatial feeling, deeper stage. #2 sounds more accurate but flat, maybe more detailed but I think the frequency response has more in the highs so that helps with details too.
I agree with those that say track #2. The soundstage is more open and it is overall smoother sounding. The difference is apparent even listening through my computer speakers (but I do have a very good speaker system on my computer). So I am curious as to which amp was which now. So was the second amp the push pull one?
The vid clearly shows when either amp is turned on or off, multiple times. In this test I preferred #1 the PP, much more detail, punch and air in the vocals. To better show/tell the difference you could use the same pre tubes and a stereo recording.
THANK YOU for that. Never having heard a tube amp output in person, you have performed a real service to me. In my opinion, track one was much brighter , and track 2 was a little mellower. They both sound great but I will be listening to my Klipsch Cornwall II speakers. So, I will opt for the track 2 sound.
Hi, nice video I'm listening to this through headphones, hope in a year time I will play this song on my own tube amp and Klipschorn speakers. Both sound great, different, but I like both - it is impossible to decide. Please can you clarify which is which, because in the comments you agreed with Rudolfo Grease, saying that the #2 is PP, but also you commented on David Newboult saying that #1 is PP and #2 is SE Please...... I'm in limbo :)
Thanks for super interesting site, Mr Ahn! I think no2 sounds flat and uninteresting compared to no1. It lacks most of the overall sense of spatial presense and life to voices and brass that is present in no1. Based on my own experiences of SE, a Reisong A10, SE Class A, EL34:s, which has the life and presense, while my solid state push-pull, NAD 317, does not, I guess no2 is Push-Pull. By the way, is it possible to get the schematics of no1, since I am planning to build a 300b-based SET amp soon? Best regards, Magnus, Sweden
#2 is pp I guess. electrically pp is near to perfect, I do not judge sound quality with my ears, only tool is my test equipment . Thank u for your great comment. Young
I prefer the second amp. Did not know which was which but after reading the comments, found out that the second amp is the single ended. Love single ended then. Thanks for the time and effort for this video.
For me, I have no preference as long as the sound quality is good. My take is the 2nd one sounds better. Thanks to Mr Ahn for the great videos, Merry Xmas!!!
1번과 2번의 녹음시 마이크 위치가 변한 것인지 앰프의 재생 주파수 특성이 다른지... 소리가 많이 다르네요.. 첫번째는 보컬이 조금 더 크게 들리고 울림이 섞인 듯 하며 그래서 그런지 음색이 밝은 것 같고.. 두번째는 보컬이 조금 작고 뒤로 물러나서 들리는 것 같고 건조하게 들립니다. 제 귀에는 1번째가 더 좋게 느껴 집니다.
Go with the logic of this situation with me you want to compare two items to a3 non-perfect item how can it be a good representation of the first two if they’re all equally fostered by in this case A mac smart phone ?
2nd immediately felt closed in and more "accurate", but first was smoother and a more relaxing vibe with a big midrange. The different pre-stage tubes radically change things here. PP depends on good feedback components and values. It can sound very bad, and there are improvements over Williamson that have been made. Often the circuit is overly complicated, so it's not done well. But if it's a DHT, I would use single ended with no feedback.
All 3 tube amps I have are SE. The only 'PP' I have are the McIntosh MC60's and MC240. I must say I love them all but the Macs are what they call unity coupled and not really PP or ultralinears. These days I listen to SE. They save me money on tubes, sound more airy, pretty good bass even at 3.5w per channel. Source is important, you need to have a good CD transport and DAC playing well recorded/produced CD's. No matter CD's, records or streaming sources, I really like SE amps for the details especially on very low volumes. Whether 300B, EL34, 6550 or KT88 and even EL84 tube amps, they sound so real and seductive that changed my opinion on SE's.
I can't skip your comment. You have strong prejudices and you were infected by audio myth severely. Science is science, thanks. Have a great day. Sincerely, Young
Yes, there is difference even thru youtube. Had to listen several times. I’m quite sure that 1st is SE. Are both amp’s in same phase? Harmonics will sound different if not in same phase.
For many years I was a fan of push-pull designs influenced by the measurements and the big manufacturers of audio machines, and I even made fun of the audiophiles for their obsession with single ended with phrases like: remind me of some unfortunate one-handed people trying to do things that require two hands .... Until one day of my visit to a sound exhibition in a hotel in Athens, I heard for the first time a well-made single ended set with D.H.T.'s and I was stunned! Since then of course I drastically changed the opinion I had about S.E. and as it turned out afterwards from my own constructions, SO, YES, S.E. SOUNDS MUCH BETTER THAN ANY PUSH-PULL SCHEMATIC. If you search carefully to internet, you'll probably find the opinion from the legend of the push-pull design -Williamson- who noticed that :
It´s obvious for me that #1 is Single Ended because the open space around and the three dimensional feeling, some thick and big compares with #2 what is more flat and to the back. The sound is not so good anyway, maybe the way to do the recording. Thank you, great and demostrative example!
@@YoungAhn Just my experience with tubes and what I heard in your test. If I correct with my appreciation..., great, I´m right; if is not..., I had a great misunderstanding and I learn something new. Thanks!
In my opinion first one is better on vocal but less low frec. Second one is better in particular low frec. Sound stage is bigger but the voice is not the same like first one.
@@vespass225 Mr Anh answers to question in a well distinguished kind. Someone ask him: Is the first one the PP? Mr Anh says: Yes! Another questioner ask him: Is the first one the SE? Mr Anh says: Yes! It seems, Mr Anh is very humorously! I very enjoy his answers, that's just the kind that makes me chuckle with prudence and delight.
@@vespass225 the first sounds more like PP, because more pressure and thicker bass, less treble, slightly muffled voices - very typical for a PP tube amp generally. the second is the opposite sound to it. less pressure, less bass, breezy like a feather, much more treble, crystal-kind voices. Very typical for a SE tube amp. I can give you a lot of more examples triodes, tetrodes, pentodes in comparsion to its SE and PP versions, you will hear everytime the same differences between the both.
Who actually commented here without knowing which was which? I bet most audiophiles changed their minds when they found out which was SE. Such gullible lot. Lol
@@YoungAhn Thank you for revealing that. That is pretty impressive if both amps are similar in response specifications and even if the PP amp is electrically better, it is clear the SE sounds much better and I could pick out the instruments on the sound stage better. With the PP amp, I could barely hear the plucking of the bass, where I could easily hear it with the SE amplifier. So now I know to go with an SE design for my next tube amp project. BTW, I am assuming in the design of both of those amps, you are not using feedback, correct?
At least please choose a better and more modern recording next time, for example from dire straits, vinyl, Thanks! From the present recording, I suppose the # 2 should be S.E. because of the no stress. Regards from Athens/Greece
It looks like the author doesn't know the results. The second take has better crosstalk and frequency response, and ... I don't like it. Even taking into account that differences in sound between those amps are so drastic (after compressing by TH-cam) - the video is useless, unfortunately. P.S.: І wish to be wrong, and the author finally will announce the true results to all of us.
I like your blind tests. But you need to find a way that we can find out the ANSWER! Or else WHATS THE POINT OF YOUR VIDEOS?? Even videos months old don't reveal the answer.
I have built a few SE amps and managed to guess right despite this not being my kind of music. SE sounds more organic (to me) ...nice amps! Thx for posting.

SE is hands down for mid freq range and thats supposed to be to enjoy. PP enhances low freq. Im 100% SE.
잘보고갑니다

For this king of music I will take #1, for rock or classic #2. So I need both, sorry ;)

소리가 많이 다르네요..
첫번째는 보컬이 조금 더 크게 들리고 울림이 섞인 듯 하며
그래서 그런지 음색이 밝은 것 같고..
두번째는 보컬이 조금 작고 뒤로 물러나서 들리는 것 같고
건조하게 들립니다.

다시 녹음할 예정입니다. 매우 날카로운 지적 감사합니다. 좋은 연말 보내세요. 세영
SET for me
Push pull sounded much better to me. Both sounded good. Just getting into tube amps.
Thank u very much. Have a great day. Young

Simple is better always
Measurement device vs ears are different..
I prefer 1 but i want to prefer 2 which i think is pp
I prefer amp 2. To me it sounds a bit warmer and less harsh than in test 1
Thank you for watching my videos.
I preferred #2 without knowing. Go figure.
How could I possibly hear any difference?
I’m watching your TH-cam video on a TV, through the TV’s speaker, and so they both sound the same.
small home theater will be OK, happy holidays
