Paul,

Your recording sounds nice and clear. I don't necessarily hear any comb filtering going on - which is what a Reflexion filter is going to solve. Now, with the Rode, you will have a greater tendency to have comb filtering going on because it's pattern has less off-axis rejection than most dynamic microphones.

Don't be surprised if you end up using your dynamic microphone. In my opinion, you already have a good sound going. I wouldn't put an awful lot of stock in getting the Rode K2 going if you find that you don't see an immediate improvement.

It's hard to give advice without full knowledge of what you have going on - but in my opinion, listening to the track above, I'm doubting that you are going to hear a marked difference. Your recording levels seem appropriate, you don't have noticeable proximity effect going on, no comb filtering audible, and your voice sounds nice.

You might play a little with high pass filtering, and peel off the very bottom end of what you've recorded, but there's not an obvious overload on low frequencies like what happens with a great deal of home recorded vocals.

In my little mic locker, I really like my EV PL80a dynamic mic, though I paid quite a bit less for it than my large diaphragm condenser - unless I'm doing very quiet whispery vocals then I use the LDC.

I honestly think that given your description of your room, that the dynamic mic might give you a better result than the K2 and Reflexion filter.
