Ah there it is… didn’t see it. Of course had to translate the page to english and for some reason some of the page didn’t translate.
“Dude, your amplifier is having trouble driving the Sonus Faber Olympica Nova 3 speakers. That amplifier is a complete disaster. A friend of mine had them and wanted to buy Sonus Faber speakers, but the amplifier could barely power them. He replaced them with E 700s, and the amplifier handled them without a problem. The E 800 easily handles, for example, the SF Olympica Nova 5 and Serafino Tradition, Dynaudio Confidence 30, where the Luxman L-550AXII amplifier would fail next to those speakers.” -
Listen, man, you don’t know what we’re talking about. The Luxman L-550AXII amplifier isn’t for stadium sound reinforcement, but for small-scale listening. Class A requires speakers with high sensitivity above 90 dB. I’m currently using Chario Aviator Cielo Ohms with a sensitivity of 92 dB, and in my 25m² listening room, it’s very loud at 40% gain. Additionally, the ODNF system, or Only Distortion Negative Feedback, is a feedback circuit with a modification where only the difference between the input and output signals is sent to the input, not the entire signal. And it rocks your Accuphase with these parameters: Rated output power:
2 x 20 W RMS/8 Ω | 2 x 40 W RMS/4 Ω
Frequency response: 20 Hz - 100 kHz (-3 dB)
Output attenuation: 200
Input sensitivity/impedance:
Motion-coil phono input: 2.5 mV/47 kΩ
Motion-coil phono input: 0.3 mV/100 Ω
Input Linear: 180 mV/47 kΩ
Total Harmonic Distortion:
<0.007% (1 kHz/8 Ω)
<0.02% (20 Hz-20 kHz/8 Ω)
Signal-to-Noise Ratio (A-weighted):
MM Phono Input: > 91 dB
MC Phono Input: > 75 dB
Linear Input: > 105 dB
Let’s just not compare the Elephant to a Rolex. 
I would have been very disappointed if a company like T+A didn’t offer Bluetooth.

Man, do you even know what a 10W difference in Class A means, let alone 70%, let alone the E800, where the difference is 150% 
A Luxman like this is a device that is in no way comparable to the E700 or E800, and that’s a league apart.
This particular Luxman isn’t bad (because the Luxman 509 is a disaster and doesn’t sound like a stage amplifier. I don’t know who could buy such a weak amplifier for that price), and a Luxman in Class A is a device that can be used to connect small and undemanding speakers. You can’t listen to anything that requires higher and much more controlled power to drive serious speakers. You have no clue what you’re talking about, because your only idea is that the equipment you own is the best in the world, and everything else, and I should add, definitely more expensive ones, is overrated. It’s a disgrace, and it’s utterly embarrassing.
P.S. Check out your Luxman’s damping factor compared to the Accuphase in class A
The E 800 can easily drive speakers like these, where the Luxman would have gone up in smoke to handle them.
A little humility and knowledge, and the fact that you own something cheaper, doesn’t mean you have to write nonsense like Accuphase is an overrated manufacturer.
Luxman wouldn’t even dream of having the sales figures that Accuphase has worldwide.
You still don’t understand. You can’t compare crude power with refined beauty. It’s precisely for refined beauty that speakers are built, capable of driving up to 8 watts of raw amplifier power.
You don’t need hundreds of watts for that!!!
Dude, you’ve got cool speakers. I’ve never heard them myself, but I’ve read reviews about them and heard a lot of positive things. The technical execution is very original. Interesting acoustic engineering thinking. Congratulations!!

“Check the damping factor of your Luxman compared to the Accuphase in class A.:”
This is not the main measure of amplifier quality. The essence of efficiency lies in matching the amplifier’s output circuit to the impedance and efficiency of the speakers
Damping factor is not the most important.
My Gryphon Diablo 300 has a damping factor of “only” 420 but it can deliver very high current.
Also the 2 x 300w at 8 ohm, 2 x 600w at 4 ohm and 2 x 950w at 2 ohm makes it can handle the most power hungry speakers like my Magico S1 MK2
So for me the combination is a match made in heaven, but very sensitive speakers may need a total different amplifier.
Thank you. These are my Holy Grail. 
I’ve been searching for them for a long time and I won’t sell them anymore. Listening to them is like flying in the sky (as Chario called them). Aviator Cielo.
One more thing: I bought the amplifier after purchasing the speakers. This was to optimally match the system.
Hi VIK - Your Dali Epikore 9 speakers are also a real blast. Congratulations!

Bitspeed,
Yes, but can you lift it? I sure couldn’t!

My first streamer was Cocktail Audio to N25. I even had a close relationship with Inho Kim from Navatron. A few issues with N25 in 2021 were resolved with him. 
What Rose is presenting by selling his devices for big money: It’s called scandal and embarrassment. I shelved my RS150B and bought an EverSolo DMP-A10. Everything works, and there’s technical support. And I paid 60% of the price of the RS151. 
Rose, you’re on a straight path to the abyss.
I agree, they both are very heavy

It should be noted that in the time that HiFi Rose have been faffing about with the EA software release version 5.10.02, EverSolo have released two finalised successful updates - neither of which bricked my T8.
HifiRose’s software development life cycle really is an absolute joke.

Damping factor is an important issue, but aside from that, the Gryphon Diablo 300 (I also had this amplifier for two weeks of testing) is a completely different design than the Luxman mentioned here. These are completely different devices that cannot be compared to the Luxman, Accuphase, or Esoteric, for example. The Diablo 300 will be able to drive, for example, the Sonus Faber Olympica 3, while the Luxman mentioned above won’t be able to deliver a satisfactory performance from these speakers, simply because it’s too weak.
And I never wrote anywhere that this is the most important aspect of an amplifier, but it is important and influences how the amplifier handles driving the speakers.
There are many great-sounding amplifiers that can drive speakers that people love, but no one in their right mind would write that what they have is the best, and generally, anything significantly more expensive is overrated, just like you. You have the best amplifier, the best speakers, the best streamer, and God knows what else you have, the best one. It makes me want to vomit just reading this nonsense.
Your Luxman is okay (because the 509 is a 200% killer, unlistenable), but your amplifier won’t drive any of the more serious speakers I mentioned earlier because it’s too weak and not designed to handle them. Small ones with one bass driver, or two, for example, on 14-cm speakers, are fine, but two bass drivers on 18 cm speakers and a sensitivity of, say, 87 dB, and that’s a bummer. Even the B&W 803d4 speakers, which have two 18cm drivers, are not very low-efficiency speakers, but are very demanding because these speakers are structurally very sensitive to high sensitivity and require a very good amplifier to handle this. Many amplifiers can’t handle these peaks, including your Luxman. A colleague tried to test this connection and the store manager advised against it. He said it was too weak for these speakers and that the much more powerful Pass, which they had in the store, should have been connected. To sum up, you like Luxman, okay, for me there is no problem, but don’t write nonsense like that Accuphase is an overrated company, because it’s nonsense and shows your little knowledge and experience with devices from this manufacturer, Luxman will not have such sales in 50 years and they will not be such devices as, for example, Accuphase, both when it comes to amplifiers and CD players.
Yes, price is the most important factor in a purchase World champion in shopping.
Could you give me the link to the store where you bought Ever Solo for 60% of the price of Rose RS 151? I’m very interested. Not that I want to buy it, because I wouldn’t buy the Ever Solo even for 50%, I prefer my RS 151, but I’m curious what kind of store sells it for such pennies.
In my country, the difference in the initial price is 24%, and let’s say the discount is about 5 % more than it would be for Rose, so overall, it’s about 29 %. And the starting price for my compatriots for a device like the Ever Solo is too high and it sells poorly.
It’s worth noting that the price is lower for Chinese customers because the government subsidizes their companies, while Korea and other countries can’t do the same due to regulations prohibiting such practices.
And this is important to remember, as it significantly impacts the prices of Chinese electronics and, for example, automotive products.
“Could you give me a link to the store where you bought the Ever Solo for 60% of the price of the Rose RS 151? I’m very interested.”
In Poland, AudioStyl Katowice sells the DMP-A10 for PLN 13,500, and Top HiFi Warsaw sells the RS151 for PLN 20,999. Man, you’re not grasping the facts. 
Reality is overwhelming you.

- again, you don’t understand!!! The L-550AXII Mark II model is designed to control the height of efficient speakers. It’s not intended to power such power-hungry mastodons as the Bowers & Wilkins 803 D4, which outputs 50 to 500W.
You’re comparing elephants to antelopes.
Get a grip, man.
