6SN7  PsVane CV-181 Mk2 “Golds

Great review. Really enjoy your channel. You should post some videos around music.

You are killing me... I want this amp and have a  Holo Audio Spring 3 DAC!!

I am happy you got to hear the Elrogs. Now time to listen to the Elrog MOs :)  .... even more linear, more extended highs, tighter bass, less bloated in mid bass, much more detailed. CRACK

As a happy Cayin 300B MK II owner powering ZMF VC and Susvara I had been waiting for this review from you.  Didn't disappoint.  Elrogs definitely on my radar :)  Love the new presentation style too! Thanks!

Don’t forget the viva egoista 845, Trafomatic primavera, and DNA Stratus in your top tier tube reviews with wa33 elite.  Perhaps sneak in the riviera aic-10 , Modwright ha300, Eddie current studio b, octave v16 + big black box, and allnic hpa5k xl.

Thanks for the video. A problem with this amp is it uses 22DE4 rectifier tubes, which are not the easiest to find these days

Danke!

The drivers look like Psvane CV 181 mark 2

Your reviews are getting better and better. Cinematography/Editing is very nice. You need much more views. Maybe there is a service that increases viewership for the youtube algorithm. I am very impressed, I expect much more reviews.

I was thinking about Envy but I found an offer for that beast thats literally 1/3 of Envy price. More tubes, more fun they say and I love to explore those glass bubbles 😅 that said it could be more reasonable choice

Did one session on video show, and one in an audio shop, the question that had been left is: Ha300mk2 or the Envy will be mine next amplifier :)

Nice review sir.
i have few questions.
so do you suggest using TT2 as pre amp rather than as DAC  ?
Have you compare 300B with Takatsuki TA 300B with WE 300B reissues product?
for 6sn7 rolling : have you try Sylvania 6sn7 jan chs vt231 navy anchor ?
thanks in advanced

I see Elrogs and I LIKE

Hi Great review. How good is the amp as a speakers amp for high-sensitive speakers? Does it have the magical  300B sound? cheers

Another great review, thanks. I have the HA-6A powering ZMF Verite Closed and Caldera. I do like the stock tubes although I’m getting good sound from some Sophia Electric KT88 tubes. I considered the HA300 MK II but the physical size and the expensive tubes held me back. That, and Zach from ZMF recommended the HA-6A over the HA300 MK II. The HA-6A drives the Verite Closed better than the Caldera so it was interesting to me that you found the HA300 MKII had no issue with the Susvara. The Caldera, and to a much greater extent, the Susvara love current. I suppose the raw power of the HA300-MKII is enough to overcome. Incidentally, I also have the Cayin iHA-6 solid state amp that is similarly versatile and has a consonant sonic signature to the HA-6A. I use the iHA-6 quite a bit as it’s always on and, as a current source, has no limits with the Caldera. Very enjoyable setup. Keep these good reviews coming. I’m interested in the Caldera and also the Ampandsound especially.

Very good, now all you need to do is to have the amp the right way around when describing its attributes.

Thank you CMA for the comprehensive review of the HA-300, I am currently pairing it with the Susvara and im wondering if in your testing were there any benefits of running them from the speaker taps vs the 4-pin XLRs from the front panel ?

Hey Koji, thangs for the good reviews. If you have to choose this tube amp or bliss audio, which one to pick for planners?

Anyone tried the qutest with this?
