First Tube amp suggestions

The Black Ice amps, heck tube amps in general, may have many of the same issues, several of those you just described are mentioned in Black Ice’s Troubleshooting section of their website. It did look like there were responses from the manufacturer so perhaps the issues in both cases were resolved, albeit with some frustration.

But you bring up a good point and that’s what I meant by being ok with Chi-Fi. You have to be ok with the idea that you are buying direct from China and you may not have a phone number to call for support and will likely end up swapping emails. If an issue does arise you may even have to find an independent repair shop. I think Black Ice does a much better job supporting their products and offer a 1-800 number. It’s up to you to decide if that’s worth the added cost.

The good news is that these are very low tech items, very reliable, and one of the few types of consumer electronics that can be repaired. Youtube channels like Skunkworks are great for DIYers. Check out Danny from GR Research, that guy rips nearly everything lol. I personally would never mod a speaker, but I’m glad there are people out there that still repair, fix and tinker. It’s becoming a lost art. .

Thank you everyone for such great information. I spoke with the kind folks at Black Ice yesterday and they were very helpful and patient. I think I will be going that route (I am now deciding on the fx10 or pushing my budget to the f11) I can already see this hobby is going to be an expensive one, but am excited to chase the sound I think many of us look for. Thanks again and will post how the my Triangles pair with whatever I end up with!

The most expensive route will be trial and error, buying, selling returning etc. My advice would be to include the speakers into the decision making process and think of them as a system. Low power tubes will sound best on high efficiency speakers, so money saved with the F10 may end up costing more on the speaker side. I’d recommend something in the high 90’s db efficiency like Zu Dirty Weekend or Klipsch Heresy. Again if you want to use your triangles skip up to the F11 at minimum. Even that will have some issues delivering bass, but it does come with a sub out connection. 

Not to muddy the waters here, but a lot of the 3D magic you heard with the SET amp and RM7si speakers was probably not in small part due to the excellent imaging/soundstage capabilities of the speakers as it’s just a core strength of the brand (although I’m sure the amp contributed as well).  Another option would be to try these RM22XLs and see if they recapture a good portion of that magic with your existing amp, and if not you can likely turn around and sell them for little/no loss.  Just another option to ponder FWIW.

@perkadin Thanks- yes the sub out is a consideration I am mulling over.  I have an older Adire Audio Rava sub I could put into the mix for now if I am missing the very lower end.

@soix I have been eying those RM22xl's and I heard them at the same dealer that I heard the RM7's years ago.  They are definitely more weighty , but I remember them  less holographic if that makes sense- Could be my memory.  they were hooked up to different amp though - cant remember which.  Thanks for the suggestion. As stated above, starting down this road will be an expensive but enjoyable journey!
