I recently ordered a PURIFI 6525sa stereo amplifier from APOLLON AUDIO. I chose the standard model with a silver exterior.
After placing my order, I saw some rather negative forum threads about Apollon Audio gaining traction.
Seeing these, I felt it was important to share my own experience to reassure others who might be feeling uneasy.
First Things First
I am not a native English speaker; this post was translated by AI, so please excuse any awkward phrasing.
I'm just a regular customer who paid the full price (including a spring sale discount) for this amplifier.
It's hard to prove this, so if you don't believe me, I recommend skipping this post.
I found the sound quality of this amplifier to be excellent. However, I'm mostly new to audio and certainly don't own any acoustic measurement equipment. I'll refrain from making detailed comments on sound quality.
From Order to Receipt
It took just over a month. I placed the order on May 29, 2025, and shortly after, I emailed Tibor to inquire about the delivery time. He replied that it would be completed by June 18. I confirmed again on the 17th, and he said there were no changes to the schedule.
However, after the 18th passed with no contact from APOLLON AUDIO, I sent an email on June 27 asking for an update. Before Tibor could reply, I received an email from UPS on July 1, notifying me that the sender had created a label and that the package was collected, which helped me understand the situation.
According to UPS records, the amplifier's shipping label was created on July 1, with pickup occurring a few hours later. Unlike reports in other threads, I did not experience a delay of several days between label creation and pickup.
On July 3, Tibor also contacted me. He attached photos of the amplifier I requested and diligently answered my detailed questions. His responses were very prompt during this period.
I received the amplifier at home on the evening of July 4. Incidentally, I created an account with APOLLON AUDIO for this order, but my order still shows "processing" on the order confirmation page.
They respond diligently if you contact them, but at least regarding delivery times, I think they should provide updates before I have to ask. Customers who have paid always want to know the accurate delivery date, and if there's a delay, they expect a reason and a new estimated delivery. This is especially true when dealing with a small workshop in a distant country for the first time. Until I actually had the amplifier in hand, I couldn't shake the suspicion that this might be a grand international scam.
Also, perhaps this is an unnecessary concern, but Tibor and Apollon Audio often send emails during their company's late-night hours. I believe that products and services should be delivered by individuals with healthy minds and bodies. Unless they are AI bots, remote workers in distant lands, or specifically contracted for night-time email duties, they should be resting.
Packaging Condition
The amplifier arrived meticulously packed in a custom-fitted cardboard box with handmade packing materials, allowing it to withstand shipping from Slovenia to Japan. Customizing cardboard to fit the product is a time-consuming task. They seem to be people who don't shy away from such effort.
Appearance and Chassis
The amplifier's appearance, at least for the silver model I ordered, was consistent with the photos on their website.
I couldn't find any photos of the product's bottom online, so I've uploaded one. The four rubber feet also serve as the screws for securing the cover.
They are Torx screws, not common hex or Phillips head, so if you plan to purchase one and don't have the tools, I recommend getting them beforehand.
To access the amplifier's interior, you need to slide the cover off. Both the cover and the chassis are made of aluminum, so repeatedly attaching and detaching them might cause the paint (anodizing?) to wear off where they rub. Of course, I don't imagine an amplifier cover is something you'd repeatedly open and close.
Some terrible devices exist where, once disassembled, you need to be creative with screw placement or apply strong force to sheet metal to reassemble them. This amplifier is not like that; it's manufactured with appropriate processing precision.
Inside the Amplifier
The internal wiring also generally appeared to be of similar quality to the photos on their website. I occasionally get to look inside control panels of industrial equipment for work, and the amplifier's internal wiring felt comparable to those of well-made industrial products.
One difference from the internal photos on the website was that the cables connecting the binding posts to the PCB were twisted in the photos, whereas the amplifier I received had straight cables with heat-shrink tubing attached.
When I asked Tibor about this, he replied that these are thick OCC speaker cables, and because the two wires are kept close together even when straight, they are designed to be as resistant to noise as twisted pairs.
I don't have the expertise to judge the validity of this design. If anyone knowledgeable could provide insight, I'd appreciate it.
Operation and Accessories
So far, the amplifier is working normally. It powers on instantly with the Wiim Ultra's trigger, and I hear no turn-on pop noise in my environment. My speakers are the B&W 603S2, which have a poor reputation on ASR, but at least I've achieved significantly better sound quality than with my TV's speakers.
When I operated the RCA/XLR toggle switch for use with the Wiim Ultra, I didn't push it in far enough, and it got stuck in the middle, causing no sound to come from the right speaker. The switch needs to be operated until it clicks. It's a small switch, so caution is needed.
I operated the front panel power switch several times, and occasionally it would get stuck when pressed in, not returning to its original position for a while. Since I've started using it, I only power it on with the 12V trigger, so I don't worry about it much, but a few years ago, another Japanese person wrote a blog post stating that their switch became permanently stuck, and APOLLON AUDIO sent them a replacement part.
No power cable is included. Some seem to complain about this, but I think it's better for users to choose the appropriate cable length and plug shape themselves.
No manuals or specification documents are included whatsoever. When I first powered it on, I was a bit worried about whether the correct settings were applied for the input.
