I think Ichos is a very sympathetic reviewer, who merely points out the good and better properties of the gear he's reviewing. In this thread you can read perhaps his merely personal views (maybe not so meant for wider audiences). If I understood right, he esteems Mentor at least technically...

I would say, with diplomacy, that I believe both Aune and Mentor are both exceptionally good headphone amplifiers within and over their price tags. In an ideal world Aune and Flux had dealers in every country. In Finland we unfortunately don't have neither of them. So I bought Aune S 17Pro from...

For evaluation we have objevtive measurements, other people's opinions and reviews, our tastes, ears and brain. If you read my last comment earlier today, you met my personal tastes and thoughts based also on other people's views, not so much objective measurements unless they have influenced...

Very important points of Ukraine and Mentor vs Aune. Term "upgrade path" might be quite problematic especially if you, in this case, sell Aune, which you like and buy Mentor because of fancy reviews. If I understand right, Aune and Mentor are soundwise really different solid state head amps. I...

Some reviewers want to point the role of amp power's role in bass quality too. I'm just now listening Raal Ca-1a ribbon headphones with Aune S17pro. 55+ vol levels are in use, but at least I feel there is plenty of headroom left and also bass goes deep. I'm anyhow quite sure that especially the...

If I've understood right Flux Mentor is a special amp concept where you can combine two mentors for huge power and soundstage especially. I guess the 2600$ price is for two mentors stack. One unit price should be about 1250-1300$. The two units stack propably is the most powerfull headphone amp...

Accurate Sound has a 14 day free trial period. I think it's a good idea to try so you can compare with/without filters by one click of the mouse. With HLC the neutral filter set for Raal Ca1a is wonderfull. If your headphones are very neutral anyhow, the effect of filters might be lesser. I...

I have to admit that I've bought Nordost Supreme Odin cables XLR and QED cables XLR from Aliexpress China. They are reasonably priced, great sounding and impressive looking cables. Anyhow they definitely should not be named as they are. I don't know have the chinese replica producers met the...

Thanks! I try to mediate this info to the audio service.

Yes. I got Ti-b1 transformer with which Raals work normally.

Thanks! I'm afraid the audio service guys are now in point where they are trying to exclude possible reasons, one after another. I was hoping there's a small chance that someone in this thread recognizes the problem and could point out some possible, even propable reasons for this kind of...

I don't know, but I'd prefer thinking it was ok. I just wonder, if someone recognizes this power on-no sound situation. Could it be the time relay, contact to headphone cable adaptor and so on. What could prohibit the sound signal to headphones? I can send the amp back, but all the expenses are...

I bought JotR from an U.S private seller, who told me that he tested it working before sending. I first tried voltage change with a voltage transformer and an adapter. I didn't anyhow first realize that the power toggle switch wasn't ok, electricity came through to the JotR metal cover and I...

I've got a strange situation with Jotunheim R version amp. It's in local audio service for voltage change and power toggle switch change. Now the electricity comes to JotR, but no sound can be heard with Raal Ca-1a's. The audio service guys and I are quite astonished of this. Any ideas of the...

I've got a strange situation with Jotunheim R version amp. It's in local audio service for voltage change and power toggle switch change. Now the electricity comes to JotR, but no sound can be heard with Raal Ca-1a's. The audio service guys and I are quite astonished of this. Any ideas of the...

Hello, my Jotunheim R is in audio service in Helsinki. The voltage has been changed to 230v and power toggle switch is also changed. Now the electricity comes to JotR, but sound can't be heard with headphones. What could be the reason for this? Any ideas would be most wellcome!

I have listened Cayin Ha-3a and Violectric v340 with Composer and imo they are both very good amp options with austrian. I think v222 might be a bit more tubey like compared to v340. Composer is so neutral, that it simply sounds very good with different kinds of amps and DAPs. Tube bass is a...

A class solidstates can be really very "tubey" sounding. I sold an OTL tube amp a few months ago for a class Aune S17Pro, which imo is clearly more tubey and more relaxed, but anyhow detailed enough. And one can drive difficult loads with A class headamp without concerns of that the amp has to...

Raal Ca-1a is really the newcomer for me, only about two weeks for listening now. Sounds that X3p really matches better with Ca1a than Susvara, at least for your likings. For me the biggest amp surprise till now has been how well the not so effective Cayin Ha-3a tube amp works with Raal. The...

I checked. Sorry, you right, there's an adapter with HSA-1b, with which you can connect Susvara or similar unefficient headphones directly to Raal connection in front panel. So the banana taps to speaker terminals ain't necessary.

I've read that a lot of Susvara users have used direct connection with adapter to loudspeaker terminals. Susvara is about 60 ohms and really unefficient while loudspeakers are usually from 4 to 8 ohms. This is a working concept. I'm not sure, but perhaps the female xlr is meant for this type of...

Ti-1b only transforms the very very low impedance of Ca-1a to usable with amps made for normal headphones. Ca-1a uses 4 pin female xlr cable to Ti-b1 male xlr to prevent wrong connections. You should not try to connect Susvara to Ti-b1!

Sorry to hear about your unpleasant experiences with Aune. I also have this older firmware Aune version with problematic vol adjustment. I like Aune's sound a lot and my simple solution is a separate DAC with decent vol adjustment. It works just fine. This is one possibility. If I understand...

I asked the service to change the fuse, if necessary. So, it should be ok.

Yes, no sound neither light, all black and silent. I have to leave it back to service with Raal Ca1a's so they can really monitor the audio output with music input. The blackness of the unit propably refers problems with electricity input. Possibly the changed toggle unit is not working. If it's...
