Is all the hype warranted

Here ya go!

Take a look of the amount of the sold listings!

If you look at the amps date made the majority of them are older models that have been redesigned.  Current models sell at a premium price with several that have been  listed over original purchase price due to the wait time.  With the significant increase in Decware’s sales since 2021 I would expect more used amps on the market…New and old.  Audio addicts can’t help but buy the next better component.  
I enjoy my Decware Torii Jr v2 amp very much in my modest system. I feel they are very well priced for what they deliver.  Are there better amps absolutely but they will cost you considerably more. 

If you’re looking for a high quality, low production, hand made in the USA amp or preamp, consider Conrad Johnson. I’ve never compared the Decware to CJ but people tend to keep their CJ equipment. They also have a “cult like” following for good reason, they just sound right… 

I've been down this road...

I was very interested in Decware so I called the company to inquire. I got their voicemail and after a few days, someone called me back. After answering a few questions, they told me the wait list was 2 years - that's just not going to work for me. So I called Raven Audio (my "plan b") and again got the company's voicemail. 45 mins later the CEO of the company called me back. We had a great conversation that ended with him inviting me to audition their gear in person with him (he also asked me to bring any other speakers/amps I was considering so we could A/B test them on the spot). After taking him up on the offer and hearing their gear (and bringing a McIntosh MA252 with me as a reference), I went with Raven and never looked back. My Osprey LE and Corvus Reference Studio Monitors are an endgame combo. You will not be disappointed. At all.

As someone else in this thread has already eluded to, I would go with a Blackhawk or Osprey. The Nighthawk is good, but the Blackhawk and Osprey have Raven's upgraded components.

A year later I was ready to upgrade my phono stage and I was once again tempted to go the Decware route. But again, 2 years is not an option for me, so I went with Quicksilver. It sounds so good. Maybe Decware is truly something special, but I do not regret going with Raven Audio and Quicksilver for my tube amplification needs. There are world-class alternatives out there that don't require you to wait 2 years just to see how it may sound. Just my two cents. 

Good Luck!

Another good option is Aric Audio for a tube pre and amp…for solid state Jeff Rowland….
