Marv's Take: https://www.superbestaudiofriends.o...decware-taboo-mk-iv-review.12214/#post-384131 Hi, I'm a random dude who lives in Corpus and I happen to know Marv. Marv knows that I am an audiophile so he drops by the office stuff so I can check it out. Most recently, Marv dropped off a ZMF Atrium headphone and Decware Taboo amp. I really liked the Atrium and stole it from Marv. When I got a chance to try out the Decware Taboo, I thought this combination with the ZMF was super. I asked Marv if I could take the amp home and borrow it. I've never loved any pieces of gear that much that I asked to borrow them. He replied that I could borrow it for an extended period of time only if I wrote a review, so here it is. For context, I listen to speakers at home. My speakers are the Tekton Lore non-floorstanding model. I have a Bifrost for a DAC and an Emotiva integrated amp. I listen to both speakers and headphones. I am going to keep my comments brief because I don't normally write reviews. I tried the Taboo as a speaker amp with the Lores. The immediate thing that I noticed was big the soundstage that expanded outside the boundaries of the speakers. This was noticeable on Yosi Horikawa's music where he went to a forest and recorded sounds all around. The downside was that I could not get enough volume from the Taboo. I like to listen very loud. I think the Lores are 94db efficient. I cannot say if the Taboo didn't have enough power or gain or if Tekton fudged the specs on the Lores. With the ZMF Atrium headphone, the Taboo has been the best headphone amplifier I've so far. Marv said he would bring in better stuff. I'm sure better stuff exists, but for me, this is the best yet. I'm familiar with entry and mid level gear from companies like Emotiva, so this for me this is the best I've heard for now. Other tube amps I've heard sounded veiled, less detailed, very warm. The Taboo is slightly warm compared to solid-state amps but not overly so. The bass is one of the highlights. There is a lot of slam. I know the ZMF Atrium hits hard, but this amp takes it to another level. There is lots of detail and textures. The mids are lush. Sound is tubey, not too much. Closer to solid state than the Freya+ that sounded more tubey. The high end was smooth with no grain. There is a lot of drive and rhythm to the music that the Taboo conveys. Bottom line is that I just liked the sound and love listening to it.
