I would pause for a moment. I am a dealer for Weiss and Meitner and although not a Berkeley dealer, I have had their products in on trade.
Weiss 204 to Meither MA3i give me pause as these are radically different sound profiles. The Meitner is smoother, more musical and much less bright. Superficially this sounds appealing, but if your system is tuned and optimized for the Weiss, switching to the Meitner is going to materially alter the tonality of your system which will become much more laid back. If this is the desired outcome, great! If not, you can end up playing whack a mole as you changed your dad now what else will you need to change to get sound back to where you like it.
Alternatively, if you ant to maintain the current tonal balance of your system I would look at a 501/502 from Weiss which has an on-board renderer. I know it is a bit more than the Meitner but will maintain your current sonic balance and might be. better choice.
The Berkley tonally is probably a better choice than the Meitner. You could also look at a Chord TT2/MScaler combo.
