the cart or the horse?

@charles1dad makes an excellent point on the Leben 300 and Luxman SQ N150. As I mentioned in my PM, I'm a big fan of EL84's, and these 2 pieces have been on my radar for a while. I'd love to spend some time with both of them. I don't know much about the Musical Paradise amp, but the value seems high. I doubt you can go to wrong with MP, and it will likely help you understand the potential of your system, and help you refine what your end system goal might be. In particular, I think the Leben 300 could be a life long piece of gear for me. I just love tube integrated amps. Follow up and let us know how you like the MP. Also, spend some time on speaker placement to maximize your systems potential. There are some great youtube videos that explain speaker set up. It made a world of difference in my system. Also, don't forget to plan some budget for cabling. You don't need to spend a bunch of money. There are quite a few nice cheaper offerings from Audioquest, Anticables, Blue Jean cables, and many more including DIY recipes.

Congratulations!!!

At the price point of the Musical Paradise MP 301 I feel it'd be difficult to do better. This is a good introduction to tube amplifiers and  I believe that you'll be happy with what you're going to hear. It will very likely sound good straight out of the box but will improve as it accumulates burn in usage.

This is a very simple tried and true circuit with only 1 output tube per channel,  very good match for your Omegas. A straightforward and pretty pure signal path and no speaker crossover 😊. Over time you can experiment with alternative tubes and compare their sound in your MP 301. This will be informative and fun. 

It you decide that you're happy with a tube amplifier then at some future time you can consider moving on to even better options. In my opinion you've made an excellent decision.  Please let us know your listening experiences and if it's what you were seeking musically.

+1 everyone

So nice to see a thread that stays on topic and remains positive while presenting information that is not always "the same".

@ticat +1 for recognizing this and stepping up to the plate with an equally positive  reminder!
