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

Per my last post, I haven't heard the Lamm monos or Vandersteen M-5HPA, but now knowing the price difference, I concur the Vandersteen amps are a great value by comparison and I'm sure they sound great. I'm looking forward to listening to them the next time I go to Stereo Unlimited in San Diego. Maybe somewhere down the road, RV might make a nice affordable (for me anyway) integrated amp to power my Treo CT's.
Regarding cost of amps, liquid cooling, and wattage. 
I don’t think it is as simple as a linear equation with cost directly proportionate to wattage. There’s more to an amp then maximal wattage output. 
Cooling an amp is an issue. Pass amps are no doubt great but can be huge w all the heat sinks and do run hot. There may be a number of reasons he chose liquid cooling but one advantage is keeping size down and avoiding noise of fans or bulk of heat sinks. It may also afford other proprietary tech and design choices we are not privy too that might generate more heat than other amp designs. It could just be a gimmick, but that has not been Vandersteen’s MO — very against his design principles. 
About 10 years ago I learned a lot about liquid cooling for computers and server centers and even military tech. It has some cool applications and can cool far better and faster than other techniques. So who knows- but it is unlikely to be a gimmick. 
By the way-just went to the newstand to get Stereophile to read that review-what month is it in? Is it November??
