Sabaj A30a announced

[ppataki]

I use my pc as a pre-amp for volume control with windows 10 master volume control. Not bit perfect but realible.

If you use Jriver's Internal Volume control then you will have a 64-bit precision totally transparent volume control - AFAIK the highest quality volume control existing today
This is what I do with all three of my Sabaj A30As (two driving my living room and one driving my home office) - I really love these amps
And can't wait for the successor model too - I do hope that Sabaj will continue with the FDA concept - @peterwen Thank you

I will try Jriver, thank.

I use the spotify pc app and Foobar2K. I use an app called "MIDI Mixer" and a Xtouch mini DAW to control the W10 master volume and app volume.

For exemple when i play a game, i can set the volume of spotify to 50% and the game to 100 to balance them.

Hello

I just received my Sabaj A30.
How to know its firmware version and how to install the new one I downloaded. I didn't understand ...
Thank you to all of you.

Sabaj A30a announced

Thank you for providing the information about the difference in sound quality. But what I want to know is how the internal processing of the D30a works. The digital input of the AXIGN AX5689 chip supports 44.1~192kHz 32bit, but it is unknown what kind of signal is actually input. The resampling...

Une application smartphone pour le Sabaj est-elle prévue ?

C'est pour enlever le télescope qui gêne le salon !

j'ai Martin Logan Sequel 2. Sabaj est merveilleux avec.
It's incredible

Back to store
Subwoofer noise in the absence of music. intolerable
Breaks and heats from 80 (volume goes to 99). On my Martin Logan speakers.
An unreadable display at 1m. No smartphone app.
At low volume and without a subwoofer, the sound is really very very good.

So after reading through all 43 pages, what is the general consensus here? Is the Sabaj A30a a recommended buy?

I was really excited initially but after seeing Sabaj pretty much dropping support for it has me concerned.

I was initially considering buying the AO200 along with an Audiophonics Evo-Sabre DAC streamer to power my Wharfedale Evo 4.3s in a fairly large room.

After looking at this amp, I figured it would be a little better alternative because of the higher power output and perceivably better sound quality, while eliminating the necessity of a DAC. So I would just need to add a streamer option which would be relatively affordable addition.

I'm concerned if the AO200 will be able to Power my Evo 4.3s.
Any recommendations??

Hi, the only thing that concerns me is the sub output, so I manually compensate and often disable the sub because my columns are correct.

But I don't regret buying the A30a, if I had to do it again, I would buy it again because the sound with my Focal Chora 826, to quote a friend's comment, is quite impressive.

Although the A30a could be pushed further with new firmware, it's still an excellent amplifier and I recommend it.

I use a Wiim Pro network player (toslink) and a Raspberry PI4 connected to the Xmos input of the A30a, it works very well to listen to my cd albums put in flac.

The AO200 has a MA12070 chips which I know very well, I have the Sabaj A20a 2019 (double MA12070) and a friend with the Topping PA3s, I can tell you that the A30a is far ahead.

I completely agree with ModDIY's evaluation of the Sabaj A30a amplifier, in particular I really like the idea (and Sabaj's implementation) of a full digital amplifier. It works very well in my setup (it's connected via Toslink to a Wiim Mini streamer) and I like what I ear from my speakers (either Elac Vela BS 403 or Dali Zensor 3). Sometimes I connect also a Martin logan Dinamo 700W subwoofer and, whenever it's needed (not often, indeed), I adjust the subwoofer output level to match that of the speakers. A firmware update would make it even better (@peterwen, any comment about that?) and allow Sabaj to get a better reputation and SELL MANY MORE UNITS of this potential jewel. @DAudioMan, as an alternative you could consider this AUDIOPHONICS DA-S250NC Class D Integrated Amplifier.

Since folks mention that the sound quality is better than a lot of measurably good amplifiers, I'm curious as to where this improvement comes from, in particular whether the Axign digital feedback somehow compensates for impedance changes in speakers across the frequency range, behaviour of speaker crossovers, or other such things. I don't doubt that it sounds better, but I'd love to know why!

Has anyone taken measurements across the frequency range with real speakers attached (both from the speaker terminals and with a measurement mic) and compared to their previous beloved MA12070-based amplifier to see if the difference is visible? If not, does an A30a owner have the equipment with which to do so?

The objective info we have is that the Sabaj A30a in mostly a cheaper "clone" of the SMSL VMV A2 tested here by Amir. The subjective info are from users of this and other amplifiers using the Axign technology (owners of the Harman Kardon Citation Amp often complain about a number of bugs affecting that model but they all claim the sound quality is very good). For me, as I've previously written, in non-critical listening situations the sound quality is virtually indistinguishable from that of a Rotel RSX-1067 that cost about $3000 20 years ago (translation = I'm very happy with it).

 

[ohnonotagain]

The test of the A2 doesn't address what I'm really interested in. SMSL's announcement of the V2 claims "the feedback accurately reflects how the wired speakers' impedance is affecting the amplifier's sound -this is then compared with the input signal and corrected in real-time." Amir doesn't test with real or simulated loads any more, so we don't get to see if that's true, or how it affects the result if at all.

Given that amplifiers are approaching "solved problem" status but speakers are still a very mixed bag, an amplifier that can correct for unwanted speaker characteristics is potentially a big thing. That should be measurable, so I was hoping that someone might be able and willing to measure it.

I understand your point. I'm no expert and probably I'm saying something stupid but I guess what you are asking for is not that trivial to achieve. You have to test a system composed by a full-digital amplifier (eg. Sabaj A30a) and a real load represented by a pair of speakers. Which speakers would you choose for the test? Probably more than one pair, considering that the Full Digital Amplifier could lead to significant improvements in performance/measurements with one set of speakers and less with others. I also imagine that the tests should be done in parallel with the same set of speakers connected to other amplifiers (eg a class D like the Topping PA7 Plus and a class AB like the Cambridge CX81) to see how they perform in that scenario. More than Amir or other specialized sites, this is something Axign could perhaps do to be more convincing about the advantages of their technology.

 

[ohnonotagain]

I think that, in theory, any speakers with some form of crossover in should demonstrate the effect - more so than single-driver speakers - and anyone with a sound card (preferably an E1DA Cosmos) and a copy of REW could measure the effect across the speaker terminals. That said, the effect of the feedback circuit may be less at lower volume levels. And as you say, you'd need another amplifier to measure against. But who on here only has one amplifier?

Topping released in early March new xmos driver for own DAC's v5.57, but SMSL&Sabaj still no. Anybody know when shoould be release actual driver. It's neccessary for the lastest Windows 11 22H2 update.

 

[DAudioMan]

So I got the Sabaj A30a a couple of days ago and I have to say I am impressed with how well it drives my Wharfedale Evo 4.3s.
Before I used to find the bass lacking on the speakers to the point where using a sub was pretty much a necessity. Now I find I no longer feel I need to turn on the sub to enjoy the music.

I need to do more thorough listening but so far I am happy with my purchase overall.

It's good to hear that. What amp did you have before the Sabaj A30a?

To troubleshoot, I think ASIO4ALL should work.

I tested "SPDIF SENS" of OPT/COAX input of A30a.
For DDC I used SMSL PO100 and PO100 AK and an old Sony Blu-ray player BDP-S6700.

For the COAX/OPT output of the PO100, it was necessary to set the setting to 3 for a stable connection, but when connecting the COAX/OPT output of the new PO100 AK, even if the setting is set to 1 for the highest quality. I was able to connect stably. Even with the same SMSL DDC, there seems to be a big difference between the old and new signal quality.
Sony's Blu-ray player also worked reliably at the highest quality of 1.
However, this Blu-ray player could not connect at all with Topping D50/D50s.

I also ordered the PO100 Pro from this result. We will test this later as well.

did you test the PO100 Pro?
