It sounds like an announcement. :) Reading between lines, they have hardware ready for shipment, just waiting for a firmware to be finalised. IanCanada is promising release next month, I expect there will be similar timeline, except with extensive product line it takes more time for testing.

It was back in 2020 Ian wrote, it was an assumption. He made it during first experiments based on a general knowledge that USB frame native DSD512 timing is the same as PCM 768kHz. In a consequence after flashing Linux optimised firmware Amanero should support PCM 768kHz too. Wrong! A maximum...

For DSD512 you only need to flash firmware optimised for Linux. With no hardware upgrades. For PCM 768kHz wait for an announcement of upgrading DI-24 with Amanero Combo768. I can't guarantee it will happen. Current restriction are specified on the website.

PCM 384kHz limit is related to the Amanero I2S interface limit. It is not USB limit, not drivers, as DSD512 demonstrate it clearly. A weakest part impose restriction to the entire chain. With DI-20 nothing you can do as Amanero interface is integrated with the motherboard. DI-24 is different...

Hehehe. Audio industry is so fragmented... LOL

Your original problem was of not being able to play anything faster than DSD128 with HQPlayer on some Linux source. Once you have learnt with examples it is possible, you are trying to bring things you don't understand and should not be your concern. You are trolling, people are not interested...

Q. Do fiber module (1) act as a repeater according to the HDMI protocol or (2) transmit logic transitions while not interpreting protocol? I don't know. Case: 1. It won't work, as I2S is not HDMI, just use the same cable/connectors. 2. It might work with 10Gbps fiber, but it will add jitter...

I really don't get how you deducted it from the Ian post. A highlighted is true. Inside spoiler I covered why it happens.

DI-24 / DI-20 support for DSD 512 Now those users upsampling to DSD want to activate DSD512. Information I give is also for trolls. :) Yes, just load the firmware optimised for Linux. There is a guide for Roon...

I think none of them have a battery. A large black rectangular box can be isolated power supply (DC/DC converter). Will verify later.

Is Rockna warranty support restricted to the first registered owner? Hardware cannot be duplicated, there is no reason to apply restrictions similar to licensing software. There is serial number, name of the previous owner, send request to Rockna, more practical approach.

Be aware, not all high-speed (or 480Mbps) isolators are based on the ADuM3165/6 or ADuM4165/6 chip! If doesn't say which chip is used, don't buy it. It may use the older refurbished discontinued Silanna isolator or something worse. By example this one is not...

A new product based on ADuM3166, with USB Type C uplink and a hub. Plus the optional connection to external power supply through one Type C dowstream port. https://www.aliexpress.us/item/3256806826164578.html I don't like Type C upstream port, but comes in a metal enclosure and internally...

It will play DSD256 as well, 90%. Once I get confirmation from you that it plays in a native mode DSD64, DSD128 and DSD256, I am sure that will play DSD512 after making one small step further. :)

From the Q7 manual application notes: 2. What kinds of DACs can a FifoPi Q7 work with? A. Any kinds of SYNC mode DAC..... However, by principle, any master clock mode DAC, such a Hifiberry DAC+, have no way work with any reclockers including FifoPi Q7.... If it means dependancy on the Master...
