DAC/w Volume control + Power amp or DAC + Integrated?

arron

Speakers will be Spatial audio Sapphire M3 open baffle.

Remote volume is a plus but not a must.

If I can not afford LTA Ultralinear int then I’m open to any amplifiers out there.
Raven nighthawk, Devialet 200, Dynaco ST70, Luxman 550s come to mind.

i have the m3 sapphires, have run these tremendous speakers with a wide variety of amps

key point of note is that the towering strength of the m3s’s is their amazingly full, natural, impactful bass imparted by clayton’s open baffle design... followed then by their excellent, open treble and full bodied dimensional midrange

that being said, these speakers have 4x 15 in woofers, presenting a load of 4 ohms in the bass region despite a seemingly quite efficient 93 db/w/m... thus they are actually quite a challenge for many tube amps (read, most lower powered, inexpensive ones) to deliver the current and damping factor (woofer control) needed to reproduce the truly wonderful bass response, the speakers’ key strength

as such, i recommend you get a high quality ss integrated amp with built in onboard dac, if you need to stay on a tight budget - imho it is the most cost effective path of excellent sound using these speakers

a lower powered current generation hegel (h95 or h120), or a small devialet (which i have - the 120 - which drives the m3s’s brilliantly), or a similar offering from ps audio or others...

at $2000-2400 for hegel (new) or devialet (used) above, i promise you will have a hard time beating it with $4000-5000 of standalone dacs and tube amps... digital volume controlled dac or not :)

you have wisely chosen such truly outstanding speakers... but a tube amp on a budget is not the right answer to make them sing at their best

good luck, have fun

Avoid a cheap volume control.  That really matters and a bad one will lead to underwhelming performance.  I have a Schiit Freya + here and even in passive mode it sucks the life out of my music. 
Hugo 2 and LTA power amp vs Qutest with LTA integrated.  I feel like the line stage and volume control in the LTA is very good.  I have had that exact amp connected too Avantgarde Zeros and they highlight anything in your setup that is an issue.  It was incredible.  
That being said, the volume control in the Hugo 2 is VERY good.  I use a Hugo 2 and 2Go for everything at home.  
The DAC in the Qutest and Hugo2 are the same.  The Hugo 2 has a volume control and headphone amp.  

I think LTA integrated with Qutest will be absolute best sound.  With Spatials?????   LTA and Spatial were in the room next to me at CAF and they sounded really good.  This is an A+ system you are putting together.  
As someone who sells both products (LTA and Chord), I am 100% sure you can be on budget with either combo.  The real question is if you want the flexibility the Hugo 2 provides

Reach out to Tommy O’Brien over at Digital Amplifier Company.  He believes in the shortest signal path, and designs his amps and DACs to this belief. I have a pair of his mono amps, his DAC, and the synergy with my Spatials produce the best sound I have had in my room.  Highly recommend you give his products a look.

Lyngdorf TDAI 1120 ... integrated amplifier .. I’m very happy with mine.. for less than 1/3 of your budged.. take a look as there are excellent reviews ..

The Aesthetix Mimas Integrated Amplifier with the built in DAC card will meet your requirements and budget very nicely.
