I have been an owner of Decware Amps since 2013...a Torii MK IV (25 WPC), a Taboo MK III (headphone amp) and a pair of Zen Signature Mono-blocks at 2.3 SET watts.
For the Mono-blocks I use a pair of Zu Audio "Souls" rated at 99 dB at 8 ohms. To my ears this is a match made in Heaven. I have not had the opportunity to listen to any of the new UFO transformers but I'm sure they are nice. I also used a pair of Omega Alinco Speakers with the monoblocks ...I think they are rated 93 dB. They weren't quite able to reach loud levels as the Zu's can. I much prefer the Zu's but admit I own two pairs of Omega Speakers and they perform much better with the 25 WPC Torii. I would suggest going to the Decware site and reading some of the comments and reviews on the forum. There are specific sections for each piece of gear...both in production and discontinued. It is a great resource. Mark.
