VAC Master 300 iQ (Original) vs MKII

[sofer]

Hi all,


I have a chance to grab a pair of the original VAC Master 300 iQ monoblocks (demo unit, factory warranty until late 2026) for $27k.


I’m currently running VAC Master Pre + 200 iQ monos with Wilson Yvettes. I love the VAC sound, but I’m looking for more authority and "grip" in the bass, and I’m curious if the 300 iQ is a significant jump in driver control compared to the 200 iQ.


My two main questions:


1 Is the jump in bass control/authority from the 200 iQ to the 300 iQ as dramatic as I’ve read?


2 Given the price difference between this "original" version and the current MKII (which is significantly more expensive), is $27k a solid deal for the original 300 iQ in 2026?


Any thoughts from owners would be greatly appreciated. Thanks!

Hi everyone,
I need a quick, straightforward sanity check.
I am currently running a pair of VAC Signature 200 iQ monoblocks with a VAC Master Preamplifier, driving a pair of Wilson Audio Yvette speakers (supported by two REL S/510 subs).
While I absolutely love the classic VAC midrange, I am looking to compare them directly to the Master Series amplification. Specifically, the Yvettes' low-end impedance dips to a demanding 2.94 ohms at 90Hz, and I am looking to understand what the larger Master series monos will bring to the table in terms of driver control and bass authority.
I have a firm offer from an authorized dealer for a used factory demo pair of the original VAC Master 300 iQ (Mk1) in black for $27,000 shipped, which includes a factory warranty until Nov 2026.
With the newer Master 300 iQ MkII currently retailing at much higher cost, I'm wondering:
1 Will the original Mk1 300 iQ monoblocks give me a significant leap in effortless driver control, bass grip, and dynamic headroom over the 200 iQ on these speakers?
2 Is the sonic gap between the original 300 iQ and the newer MkII significant enough to justify waiting/paying more, or does the original Mk1 at $27k represent the ultimate "sweet spot"?
3 At $27k with a warranty, does this feel like a fair and correct price for a Mk1 demo pair?
I’m ready to make the purchase, so I would highly appreciate any final thoughts or feedback from those who have compared the 200 iQ vs. the 300 iQ (especially in a full VAC stack).
Thanks!

Don't get hung up on a warranty that expires in 6 months in your decision.
