2a3 for me .

[@VirtualHiFi]

Thanks for sharing

[@michaelcorlet2998]

Excellent vidieo.for the first time i can clearly decern the difference.2a3 more organic.kt88 has element of hardness,edge. Well done. Music ex choice.

[@rodm1949]

Just ordered a KT88 and listening for what I'm in for, yes I've made the right choice for now. But I feel a pair of singles will be on my christmas list. Love your panchance and leaving all the guess work to the viewer.

[@briangurnett]

Fantastic. Subscribed. Can you please share your playlist? Some tracks were new to me but all were EXCELLENT.

[@manuelreyes1908]

Great video. Great sound, 2a3 for me!! More balanced and open. Could listen for hours.. I had 300b push pull mono blocks as main power unit. Once I tested a 2a3 SET there was no way back.

[@VirtualHiFi]

Great to hear! Thank you for your comment ;)

[@jdsalinger73]

KT88. I don't have golden ears, but what I noticed is a much more thin sound on the 2A3. 2A3 has better decay and delicate details (nicer reverb) I've built a 6B4G SE direct coupled amp and for the added complexity, it isn't any better than my cap-coupled SE el34 and way less power. Just can't justify it. Honestly, if I build another amp, it will be the humble 6BQ5 SE.

[@VirtualHiFi]

thanks for sharing 😊 yes 2A3 is a very balanced and not warm tube. so for tuby sound other tubes are more tuby ;)

[@kenturmon3660]

2a3 is def one of my favorite tubes.

[@VirtualHiFi]

I like it very much as well 😊

[@matytinman]

Fezz Audio Mira Ceti 2A3 SE is the winner without any doubt.

[@VirtualHiFi]

Thank you for sharing your winner ;)

[@glenschneider5978]

I like the delicacy of the 2a3. Totally worth the power trade off to my taste.

[@VirtualHiFi]

Yes most people consider it more natural and refined. But the speakers need to have some SPL

[@fliegerb777]

PP KT88 gives more clarity. Some notes/harmonics were missing (suppressed?) from the violin in the Storm (Vivaldi) 10:04”. I recognized the notes because I kept hearing this piece everytime my son practiced to play that piece long time ago with his orchestra group (multi violin players).

[@VirtualHiFi]

Thank you for your comment and sharing unique perspective. That it very interesting :P)

[@ДмитрийФазер-н3ъ]

first song sax on 300B sounds deeper and bigger, more comfortable. On female vocals low mids are warmer and wider on 300B, but more clear and prononced on KT88. On electronic KT88 have deeper and better shaped bottom end. Very difficult choice)) I would choose 300B SET as more pure and minimalistic design and leave loud and powerfull musik for transistors))

[@VirtualHiFi]

thank you for sharing ;)

[@kavimaniworld]

Thank you for the great comparison of SE vs PP amplifiers. your audio recording from the speakers are very nice. What is the setup of the mic to record the audio form the speakers. Thanks in advance. MK

[@VirtualHiFi]

Thank you very much. The recording gear is Soundedvices MixPre3 and Shoeps CMC6MK4 microphones ;)

[@davidefracassa4051]

2a3 thank you

[@VirtualHiFi]

Thanks for sharing :)

[@pesoso78]

KT88 is suitable for more genres of music

[@VirtualHiFi]

I totally agree 👍

[@thierrybernot9369]

KT88. More grip on the upper bass and … soft on the voices at the same time. Strange I heard more distortion on the 2a3 a few times on the upper mid range (feminine voice).

[@VirtualHiFi]

Thank you for your feedback

[@kindface]

KT88 soundstage better envelops the listener, more 360, and better separates each instrument. The 2A3's soundstage has noticeably less width and depth.

[@VirtualHiFi]

Thanks for sharing ;)

[@lazdow9229]

I liked the KT- 88 amp better but they both really sound good. Thank you for this comparison.

[@VirtualHiFi]

Thanks for watching and for sharing your feedback ;)

[@nicholasgoh3526]

KT88 is the most solid state sounding tube.

[@VirtualHiFi]

Thanks for sharing and I totally agree 💯

[@tejkarangehlot4741]

Very very nice sounding speaker sir.. which brand??

[@VirtualHiFi]

Thank you for sharing your opinion. The speakers are Cube Audio Nenuphar - www.cubeaudio.eu

[@yerifan3161]

KT88 more dynamic and fuller 2A3 more easy listening

[@craigenputtock]

Thanks for making this effort.

[@VirtualHiFi]

My pleasure! and thank you for subscribing :)

[@michelcouture7026]

I use a elekit Tu 8900 that can be uses with 300 b 8W or 2A3 3,5W in sigle ended , it is relay nice , tube rolling with cassor Linlai we300b or PsVane 300b acme or Linlai E series 2a3 or cassor We2a3 or EH 2A3 from Electro Harmonics. It is like i have several. 2A3 are like you where there, 300b have a velvety sound. I also have Vtl mono that uses EL34, they are more powerfull but less airy , less detailled, even in triod mode. For critical listening i prefer 2A3s. I was rely surprise at the spl that I can expect with 2A3s. With moderate sensibility speakers (91 db).

[@VirtualHiFi]

Thank you very much for sharing your comment :) I agree with you about the overall character ;)

[@briancampbell7712]

the single ended doesn't seem to have the strength that the push pull does...the push pull drives your speakers a little better...would love it if you had some James Taylor music playing...this isn't music I listen to so it's even harder to compare

[@VirtualHiFi]

I agree and since I like a bit more power than the 2a3 can deliver, I'd go for a PushPull amp here ;)

[@hrvojekant9415]

Great demo...Thank You!

[@VirtualHiFi]

Thanks for watching!

[@MrRourk]

Just get a big enough single end like GM 70 tubes or GM100 tube.

[@tejkarangehlot4741]

Wow.. very knowledgeable video.. just subscribed

[@VirtualHiFi]

Thanks and welcome ;)

[@nuttyl283]

SE with full Range listen softly quite relax such as 45 SE 50 SE 211SE 4P1L PSE but need high sensivity speakers otherwise distortion is high.

[@VirtualHiFi]

Totally agree ;)

[@bankdobrychmonet5511]

I try both kt88 and 2a3 on my 4p1l se and both sounds good

[@villageroma]

Best topology is running say an EL34 push/pull pentode with some negative feed back.

[@kubockferre5532]

hi,I prefer kt 88

[@adrianzamfirache1789]

2a3

[@VirtualHiFi]

Thanks for your vote :)

[@iviv1940]

2A3 amplifier is only 4wt per channel? Isn' it too less for average speakers? Does it work only with some models of widerange speakers (not even any model)?

[@justins.4839]

U need a pretty efficient speaker typically like 93db sensitivity or higher.

[@logotrikes]

Maybe my ears are glued on. Little difference to me, either would do although I like SET....

[@VirtualHiFi]

The difference is definitely minor, so you are partially right ;) with good set of headphones you will hear the difference for sure ;)

[@paolo60333]

Maybe you have forgotten to compare a SE triode amplifier with a P-P triode amplifier. Since I love triodes and not pentodes this would have been a good chance to compare triode amplifier only. With the pentodes of course we get more distortion. So I dismissed them many years ago

[@VirtualHiFi]

Tried push pull amps are a very rare thing. Do you know any good popular amp that you recommend I'll try to get one for tests ;)

[@paolo60333]

Unfortunately I don't know any triodes P-P amplifier in the mainstream (maybe the VAC built some of them). I own a pair of DIY triodes P-P amplifiers with 212C tubes since I drive a couple of Sound Lab speakers and I am very happy with them

[@TheOsharaf]

Audio Note Soro PP uses dual triodes

[@VirtualHiFi]

That is interesign :)

[@TheOsharaf]

@@VirtualHiFi Hoping to see you test it soon

[@stancip]

Hello for 2A3 amp like Fezz Mira - can i use a speaker with 97 dec but only 4 ohms ? Thanks

[@milosbicanin9231]

that is what I am also interested to know

[@jareksuski1478]

what is the artist in4 minute vocal/vinyl

[@alberto3028]

KT88

[@VirtualHiFi]

Thanks 👍

[@KimvonEssen]

2A3 every day, so much more non fatigue than push pull!

[@VirtualHiFi]

Thank you for your vote

[@dennis3779]

Nice. Now throw in a SE kt150 and SE 300B amp and then again with some less sensitive or less easy speakers 🤔

[@dennis3779]

SE is always purer

[@csabazsambok1258]

For me 2A3 is better.

[@VirtualHiFi]

Thanks for sharing :)

[@lorenzomiolo8735]

2A3s sound more "open"

[@VirtualHiFi]

Agree with that ;)

[@lynnmaloney471]

Kt 88 by a little 🎶

[@VirtualHiFi]

Thanks for sharing your opinion

[@davidnguyen5028]

Lots of noise on your recording.

[@VirtualHiFi]

The noise comes from the music. the tracks have such character ;)

[@evgenijlaramov1454]

я бы выбрал 2а3 + саб на германиевом усилителе с пасивным излучателем..

[@evgenijlaramov1454]

- музыка однообразная..нет муржского вокала и кантрирока
