Upgrade Quandary: Ref 75SE vs Ref 150 (non SE)


I have a ARC Ref 75 (non SE). I’m trying to decide whether to upgrade it to the 75SE through ARC or sell it here and buy an ARC 150 (non SE). For the sake of this debate, let’s assume costs are equal (I know they are not).
Here’s what I’m after
1) More control in the bass
2) More control in upper midrange (same as bass note above)
3) Not deviate too far from the other elements of sound I have.

Room: 21deep x14wide x10high
Dedicated audio

Gear:
Wilson Audio Sasha (1)
Lumin T1 source
ARC Ref 3 pre
ARC Ref 75
Transparent Ultra g5 balanced ICs and speaker cables.
Bass traps in 2 front corners, 1st, 2nd reflection diffusers.

Thanks MUCH!
P.S. No I can’t audition either amp. in my system.
P.S.S. I’ve auditioned a couple solid state amps, they don’t do it for me. Much more bass (too much) and complete control was found, but they gave up too much in too many areas, like air around the instruments and voices and bloom that I love about tube power.

 If it were me I would go for the extra power of the Ref 150. You can always upgrade it to an SE some time in the future if you want. I am not sure how efficient the Sashas are but the extra power should give you a bit more control. My Sonus Faber Elipsa SE are 92db and I have a Ref 110. I preferred the extra power of my Ref 110 (with KT120 tubes) over the Ref 75.

  I would also consider upgrading your Ref 3 to a Ref 5se. The preamp can have more affect on the sound than the amp. And the Ref 5se is a huge upgrade over the Ref 3. I chose to keep my Ref 110 and upgrade my preamp a year or so ago. and again recently I decided to upgrade my phono preamp to the matching Ref Phono 2se and not upgrade my amp. Eventually I will upgrade to a Ref 150se but I feel no real urgency. At this point I am truly happy with the sound of my system.



 I totally agree with gpgr4blu. You could always the Ref 150 upgraded by ARC to the SE version later if you felt the need.

The difference between the Ref 3 and Ref 5 is not that big. The difference between the Ref 5 and Ref 5se is much bigger. The difference between the Ref 3 and Ref 5se is substantial. The Ref 5se is just magical with a huge holographic soundstage. If close my eyes and I would swear there is a piano in my living room.

 I also agree that isolation is very important. When I went from a Solidsteel rack to a maple rack I could hear an audible difference. Maple sounds smoother, less mechanical at least with tube equipment. I noticed the biggest improvement with my amp. I now have a maple Zoethecus rack with the Z-slabs. Each of the shelves is layered with RF shielding. I have each piece sitting on large stainless steel cones.  The other thing that made a big difference was replacing my power cords with Shunyata Alpha HC cords. They just enhanced all the great qualities of my Ref 5se.
