Favorable Hypex amplifier review...
« on: February 24, 2008, 05:47:36 pm »

I just finished building 2 UcD400HG monoblocks from Hypex.  I found out about them from this forum.  They replaced a bryston 4b for my mix room.  I have had the opportunity to use them on 2 mixes last week.  Overall impression is very favorable.  the monitor chain is Digital out of the digidesign 192 interface to an Avocet.  DA of Avocet to the Hypex amps.  Amps to ProAc studio 100 monitors.  

Immediate impressions for me compared to the Bryston4b.
1) mid range a bit more forward.
2) low end more defined.  
3) The high end seemed similar.

I had a bit of a problem at first because the Hypex UcD amps sounded much cleaner than my bryston. There was less stuff around my instruments and vocals in the mix.  I was not used to that but i adjusted after the first mix.  I really like the detail in the Hypex.  In defense of the Brystons they are 8 or 9 years old.  so perhaps a tuneup would have compared more favorably.

I am not sure how these amps would fare for a mastering engineer used to ultra high end amplifiers.   but for me it lifted some haze from my speakers.

But the Hypex is better than 99% of what passes for "high-end!"

I wish there was a dealer in the US that would lend me one to try....

as i'm in Brussels,
Bruno Putzey was kind enough to bring me 2 amps based the UCD700hg modules for a listening test "in situ"

i was very curious to hear how it could compared to my bryston 4Bsst powering my pair of PMC IB2S

Bryston-PMC is supposed to be "The" perfect match ...
Hypex-PMC is the new one

at least for me
after 3 hours of critical listening, i could figured that
these 2 monoblocs had a very good balance and an overall impressive transparency.
the hypex had a better sound stage & imaging ,
the overall sound was extremly detailed,
but what impressed me the most was how the bass translated,
with a definition i never heard before with the bryston,
i haven't mesured it but i think it extended the low frequency response because of the better bass management.



i've ordered a pair ...

In my case I think Ive figured out why my Hypex in the mid range and bass is much clearer than my Bryston 4bs. As I posted before there is just less stuff around the vocals and instruments.  So that in effect gives the mid range a forward impression to me. the same applies to the bass range as well.  It is just more defined.  
after almost 2 weeks on  my UcD400hgs mixing Ive noticed as well these amps are a tad brighter than my Bryston 4b as well.  It is subtle but definitely brighter.  If I translate in terms of my mixes I would say If I had an eq across my mix buss i would be about 1 to 1.5 db lower in high freq eq .  my mixes are translating very well to other systems.  the sound is definitely accurate and very clean.  I am still getting used to hearing this way from my speakers.

I've had my Hypex UcD400HG amps for about two months now and I agree the new formula is Hypex-PMC (MB1 in my case). Just clean, clean power. I didn't notice any spectrum changes but agree that the clarity of the bottom is much better. The lack of any discernible distortion is amazing.

Good to know others are hearing the same things. Bruno rocks!
