Vandersteen's new affordable mono blocks at the CES 18

Just got an email that his new amps will be unveiled at the CES.  Here is what I got.  I can't wait.  He has adjustable crossovers so you can use them on any speaker that doesn't go down to 20HZ, which is 99% of teh speakers on the market.  Here is what they said:

Vandersteen Audio Introduces the Next GREAT Amplifier at CES 2018!Venetian Suite 29-203
Vandersteen Audio shook up the audio world with its liquid-cooled M7-HPA monoblocks, a radical advance in power amplifier design and loudspeaker performance that is Stereophile Class-A rated as a true reference.Vandersteen is doing it again at CES 2018 in Las Vegas, where you can get the first look and listen at a pre-production pair of the upcoming M5-HPA (High-Pass Amplifier) monoblocks! The M5-HPA is a solid-state design descended directly from the flagship monoblocks. It will be substantially less expensive, but will offer an astonishing amount of the flagship's sonic magic. While the M7-HPA is designed specifically for Vandersteen's Model Seven Mk II speakers, the M5-HPA will work with a much wider variety of loudspeakers and Vandersteen powered subwoofers. To accomplish this goal, while the M7-HPA's high-pass is fixed at 100Hz, the M5-HPA's internal high-pass filtering is adjustable to any of the following five settings: 20Hz, 40Hz, 80Hz, 100Hz, 200Hz.Vandersteen for years has employed high-pass filtering with powered subwoofers for the ultimate in powered-bass performance. When paired with a Vandersteen powered-bass speaker like the Quatro Wood CT the M5-HPA forms a complete powered-bass speaker system in which the amplification is perfectly optimized over the entire frequency range.
Richard Vandersteen is responsible for the M5-HPA’s overall design and architecture; the amplifier was developed and is built in partnership between Vandersteen Audio and Dean Klinefelter, a talented designer and engineer in his own right. 
Vandersteen powered-bass speaker systems are the ultimate expression of Richard Vandersteen’s philosophies on design and performance, formed over decades of industry-leading design & research & innovation.
M5-HPA's technical attributes:
  • Zero-Feedback Solid-State Design With Dual Single-Ended Circuits Connected By The Speaker Load
  • All Signal Transistors N-Channel Bipolars 
  • No Emitter Resistors
  • Minimal Circuit Path- Only 5 Parts In Signal Path Per Phase
  • 10 Separate Power Supplies
  • Adjustable High-Pass Filter (20Hz, 40Hz, 80Hz, 100Hz, 200Hz)
  • 300-Watts Into 4 Ohms / 150-Watts Into 8 Ohms
  • Made In The USA

I got that same e-mail this morning. Very interesting, but I doubt I’ll bite. One thing not mentioned, how much will they cost? If they are under $10K they may be competitive, but more than that they would have to be pretty impressive. I’ve got a PS Audio BHK 250 which works quite well with Model 5s, but I do have to use the crossover boxes. The BHK amps are pretty damn good, were designed by a legend in electronic design, and is said to be his best work to date. All that for $7.5K. Richard is a legend in speaker design, but electronics? Not knocking Richard, just saying there is some tough competition. Vandersteen also states that the M5-HP amps are aimed at a much larger market than the M7-HP amps which are really just for the Model seven speakers. The M5-HP was almost certainly designed with Model 5, Quatro and Treo in mind, but not specifically for them. I’ll wait for the reviews (if I am still reading audio mags then) to see what they have to say (most likely a gushing review).

Judging from what I heard of the 7HPA, I think that these should be excellent amplifiers.  But I would suggest you title your post "more" affordable--the price hasn't been set and even if they are half or even a quarter of the price of the 7HPAs they still will be very expensive. 
Agree that price is a big open question here. When JA reviewed the 7HPAs, he pined for a version with broader applicability....let’s see what he says when he gets his hands on these.

Also, the nitty gritty of the 7HPAs (and I assume the 5HPAs too) was deigned by Dean Klinefelter, who's no schlub.   I think RV set the design parameters and DK implemented.
I'm guessing in the 15k range.  I know how Richard designs and he took 30k amps and made one that he and the other designer felt was better.  He's been working on this one for a while now.  I have spoken to someone who's heard these and said they are a game changer for the price range they are in.  

I'm currently using the Ayre AX5/20 integrated and I like it a ton. I got it over most of the 15k amps out there as I was also willing to get a used Audio Research or Aesthetix preamp to go with it.  For me, the difference in SQ wasn't worth it, so I went with the Ayre.  I have a feeling that this one will be for me as I know and trust the person who shared with me. 

I personally may share reviews on forums, but I never audition based on them. The are just fun to read.  There are only a handful of folks who I know and trust who review, but that's me.  I get out and audition a ton, so I have a great idea how they will sound to my ear, compared to teh competition.  

BTW, Richard is a great designer. Just because he has designed only speakers up to now, don't think he can't design great electronics.  He even brought in another designer to help out.  He's packed a lot into these amps.  I'm pretty stoked to get to hear them once he gets teh full production models out.
the new amps are factually $15 K the pair, the CES flyer will say preliminary pricing but if any of you have ever built anything of substance with hundreds of parts and a complicated supply chain that should be understandable. I have not heard them yet but I have spent the last three very enjoyable days and evenings ( very late sleep deprived listen all night kind of evenings) listening to his M7-HPA in my system. They replaced a no slouch Ayre VX-R Twenty.....

i will write a detailed review at some point but so far on no parameter would I go back to the Ayre.

on the point of amplifier chops. Dean is the man behind PSE which were giant killers, try to find one - people dont sell them for a reason. i think RV’s unique speaker and amp designer experience ( where do you think all the feed forward, power factor corrected sub amps came from ? ) drove some very unique engineering solutions into the M7: liquid cooling, no emiter R, cyclotronic SS topology, tube front end, built in power conditioning, DBS and HRS isolation....the list goes on

ya i am biased...

but wow am i happy listening...

now back to The Wayfaring Strangers - Shifting Sands of Time....sounds like microphone feeds off my high speed Revox

great music choice!!!  Thanks for sharing thoughts on your amps.  They really are special. I owned PSE for a spell, but needed to make a change adn the money was right, lol. I didn't realize Dean's masterful pedigree.  I can't wait to get a pair in my room to listen to them.  Smart move on their part to also have a 20hz crossover so that it's basically a full range amp that anyone can use since hardly any speakers go lower than 20hz and if your's do, I"m sure that you will be using amps at 30k or more most of the time.

I like the look too.
