Upgrade my HiFi setup!

Personally I think Monitor Audio is highly underrated/undervalued, but I don't think the sound will be the same.  The mid-treble in particular will be different and you should be sure of your choices. 

Thanks for your help guys!

You can add the KEF KC62 sub to the mix and get the LS50 Meta. That is a surprisingly great sound in a small-ish space. 

I replaced the LS50 Meta + KC62 sub with the Magnepan LRS+ and then the  Magnepan Mini. I went to smaller office spaces. The Magnepan Mini is using the same panel as the 3,7 but much smaller.

I think the following would be great:

• Magnepan 3.7 speakers (used)
• Schitt Audio Wotan amp ($2k)
• Benchmark LA4 preamp ($2.5k or less used)
• Schitt Byggi DAC ($3.5k) (has a digital volume control as an option)
• Benchmark XLR & RCA interconnects (low cost and great for Benchmark and Schitt)

My office setup is the same except I have the Mini speakers. This thing sounds so good. Do not be fooled by the low cost of the Wotan amp, it is superb, but it needs a lot of play to settle into my current sound. I do not have the Schitt Byggi DAC yet, I am in the queue to get it in the next few weeks. I have the Schitt Yggi+ OG on my office system and if they still sold it I would easily reconned it over the unheard Byggi. Though rumors are that the Byggi is the best DAC they ever made.

BTW - I recently heard a preamp that I liked better than the LA4. That was a tube preamp which was as detailed as the LA4 but with tubes. It cost $33k.

I also heard a tube DAC that I liked better than the Yggi+ OG DAC, but that DAC cost $24k. Only 2 items I would consider changing the LA4 or Yggi+ OG DACs for. Luckily, I cannot afford them.

Well I would go big or go home...stop messing around.....get 300B amp and a pair of speaker like the Devore O/baby Speakers.....please don't tell me they don't have the bass you "feel you need" ...forget room size what matters is your sitting position in relation to the speakers...you don't need a PA system to fill the room that is all BS...If you have a DAC with a volume control and you are not listening to vinyl that that will work...start there. You can easily rival the "big time-expensive systems " start with the music that moves your soul.

With respect to your speakers only, if you are happy with the stand mount set up, I would consider a pair of Dynaudio Contour 20i's or better yet the confidence 20's. 
They are better.  The big advantage of the Confidence 20's, besides the better tweeters, is the down firing ports that allow closer placement to the rear wall.  I replaced very large Revel Salon 2's with the Confidence 20's and they are better in all ways.  Their ability to scale in a large room is phenomenal.  I  do use a pair of REL Carbon Specials. but even turned off the Dynaudio's are impressive.  Resale value remains good as well. Note however that they crave power and current, and reward good electronics.
