[QUOTE="Wietsche, post: 877577, member: 18941"] Hi, Here is an extract from another forum where Andre from Allo.com explains: "As you may have seen on the site, we have released a notice : The Katana is a complex DAC that offers multiple filtering and powering options.The pursuit of the best sound quality is what drives our design team and the reason behind our recent decision to halt manufacturing of the late KATANA. A new version, the 1.2, is in the works and will only have a few components changed resulting in a subtle, yet necessary SQ improvement. Please note the following: No orders will be accepted for the next 14 days. Already received your KATANA? A new one will be sent to you once the K1.2 is released. Already placed an order ? You will be soon contacted by our customer support team. Thank you for your understanding. technically ... We improved the LPF on summing opamp. Small improvement in SQ We improved filtering before analog stage . Medium improvement in SQ We improved noise escaping DC/DC convertor. Not quantified yet We connected earthing to board (with Nirvana PSU it will be automatic). Removal of some HF and better trebles . I would say small improvement but clearly audible Adding some 220uF caps to analog stage. No improvement" I am sure it's worth the wait for the newer hardware version of the Katana. Will let you know when I get it. Cheers, W Sent from my SM-N950F using Tapatalk [/QUOTE]
