ARC's new REF-75


I read Paul Bolin's review of the new REF-75 in AudioBeat and was really taken by it. So, this past weekend I drove down to Newport Beach and attended The S.H.O.W. to take a listen. In spite of the room being a bit bright, I could clearly hear the advantages this amp offers.

The REF-75 is physically beautiful with a kind of retro look. Must have been the meters. I love the looks of this amp! I placed my hand on top of the amp and it was barely warm to the touch. It runs really cool in spite of not having fans. Another advantage ... no fans ... no fan noise.

Right off the bat, the REF-75 was so grain-less, it was simply amazing. The sound comes out of a perfectly black background and the inner detail is amazing with great decay on vocals and simple instrumentals. I love classical guitar and small jazz groups, so this is right up my alley. Vocals were amazingly clear and realistic as well because of the lack of grain. Separation of instruments is another VERY strong point of the REF-75, adding realism to orchestral music. Tonality is one of the first things I listen for ... and this amp is right up there with the best of the ARC amps, including the big REF Monos. The demonstration was made using Wilson Shasha speakers ... 87db, and the meters hardly moved at all even while listening to full orchestral music. The darned thing just coasted no matter what was thrown at it. So, dynamics are terrific ... the amp supposedly uses the same power supply as that in the REF-110, so that would account for the dynamics and particularly good bass punch and depth. Huge sound stage as well. Width, depth and height were more than expected ... in fact, huge in every way.

The REF-75 I listened to at the SHOW was a prototype, but based upon what I heard, I'm buying one later this month. I've owned and/or listened to a lot of ARC amps over the years, and I can say without reservations, that this is one of the very best amps ARC has ever done. The release date is toward the end of June and the retail price is scheduled to be $9,000.00 US. Oh, and if you own a REF-110 ... sell it quick!

As a further note, I visited the Optimal Enchantment room and auditioned the new ARC REF-250 mono blocks. Randy Cooley, the owner of Optimal Enchantment, had the system set up in a suite and really had the system/room dialed in. Randy always has a great demo and has an impeccable taste in music. What I heard in Randy's room this year was simply magic. It had me shaking my head in disbelief wondering how much more information could still be hiding in those record grooves. Was it better than what I heard in the room that demoed the REF-75? Ahem ... it was, after all, Randy Cooley's room. :>)

And so, I can safely assume that you know very well the rest of the system too.

Have a nice day.
Good post Oregonpapa..
Agree the new REF amps sure packs power and that they'll drive almost any speakers sufficiently. However much also depending on the room size, how loud you normally listen to, and the types of music.

When mood kicks in, I'd sometime like to blast my system a little and feel that excitement of room being pressurized--the REF150 just barely made it. Of course I'm talking dB levels where you actually feel waves of air surrounding body--loud. Thus got me thinking during those moments of the REF250.. Not that I need them, but sometimes good to have reserve watts up the sleeve. I'll stick with my REF150 for now as a single stereo chassis is preferable in my set-up. So far they've been performing flawlessly and I'm just about to pass the 500 hour mark--once settled, it's a great amp!

So just a little heed of caution there to better try the REF75 out first in your home/system prior when possible to see that they'll not only drive your speakers, but drive them with aplomb. In another system I'm familiar with, driving Sashas in a 4x5m room, the REF150 seems to have ample reserves. My speakers are slightly easier load, but in a bigger room.
I thought so too initially. Now after more than a couple of months with them, realized
my earlier impressions don't count. From 100-400hrs with their roller coaster of ups and
downs make it rather difficult to guess what to become of the sound.

Only after passing the 400 mark it stabilized then became much more relaxed,
real/organic sounding, and continue to bloom there on. But still, if the typical 'warm thick
full euphonic' tube coloration you are seeking--they are not.

Love the cool retro metered look of the REF75, yet also the REF150 for its understated
simplicity.
Quote: "213cobra---I don't agree. Any combination of hifi gear claiming fidelity can
and should perform any kind of music "well." Perhaps not perfectly, but
certainly well. If it cannot play a full orchestra, Andrew Bird, Jack White, James Blake,
Sierra Leone's Refugee All-Stars, Gillian Welch, Led Zeppelin, Doc Watson, M.Ward, the
full international catalog of MA Recordings, Sonny Rollins, Gram Parsons, Justin Earl,
Tom Waits, Hound Dog Taylor, Alison Krause, Kate Bush and Maria Callas with equal
credibility, then a system is too skewed to genre."

---------------------------------

I don't see no Sade, Boney M, UB40, Sergio Mendez, Fourplay and the likes? And how
about some '70-'80s Disco and '90s Techno? ;p

I too have taken that so called 'purist' route (less is more thinking) at one time and have
enjoyed them quite immensely. Too many stuffs to list within that decade or so. Two of
the best sounding and most memorable amps that I have owned amongst the low
powered ones was AN Ongaku, and for mid powered unit, the VTL90 WE300Bs Triode
Monos (modified). Agree that they could sound magical, bordering surreal at times,
tears, goosebumps--aplenty for sure. Play some Ella, Nina Simone, Carol Sloane, Shirley
Horn etc. you'll be transfixed by the pureness of tone and lit from within quality that
good SET amps provide--they'll melt you for sure--literarily. But put the wrong music
at the wrong volume--they falter. Realizing then that my system began dictating my
music buying choice--I moved on.

In the end, which ever route one chose to take, it should be *music* first, and not
otherwise. As the saying goes--"There are many roads to Rome.." *Keep a
GPS handy in case you get lost! :)
Note the music I listed do not necessarily tax on watts/current, but more of speed, continuos mid bass punch/power/drive/agility.

Honestly, my turning point and what got me to re-think my whole set-up was when some friends, took few CDs off my rack--a couple of R&Bs, UB40, Sergio, and the Hugh Masakela's Stimela and played them on my then Ongaku, Tannoy, ML 30.5/31.5 (Jadis, EAD D/A as alternative) set up. They blasted them way up (not to room pressurizing level yet btw.), soon enough began winching and one commented.. "Why the hell spent so much when you can't even get to enjoy some real music properly". Sad, but quite true.. Bass was there--plenty, but just couldn't catch up in the speed, control and socks dept, and those 'continuos bass drives' at 'continuos loudness level' sure is a spell for disaster causing lower powered amps to clip and get mushy much too soon.

Hence, the prelude of my new quest.. VTL90s and on and on and on.. Got too engrossed into modifying this one, spent too much time and money on them, was basically listening to tubes, resistors, caps, wirings etc2 day in day out that music was no longer top priority--thought this was wrong, so sold them, but regretted since. (and yes, I think this particular VTL is a keeper, if ever they re-release, I'll buy them over).

Back to ARC new Ref series amps. Their availability, price, power, brand, good after sales service and re-salability in my country is what, for me, make them an attractive buy--the whole complete package. In a well balanced enough system, with some good simple tweaking, you could certainly ameliorate their weakness (if any), fortify on their strengths and make them sing--no problem, ime.
Hi Charles,
I've tried..
2 Tannoys, 2 Pro Acs, 1 AudioNote speakers--owned. Accapella, Avantgarde--
tested. With numerous various SETs owned/borrowed--too many to name/remember.
It wasn't amp-speaker matching issue in my case, probably more of the very diverse
musical genres that I listen to. Room size (my old space is larger than current), and
loudness level that I sometime like to crank the system up are determining factors too.

Will a full blooded sports car take me to the Ball, sure it could.. Can a limousine
accelerate fast and cruise me effortlessly at 120mph, yes certainly. But depending on
occasions, one is clearly made to be better/suited than the other. Hence, if you love
speed and often hit the highway, yet use that 'one' and only car you have for weekends
with family too, then getting rides such as Panamera Turbo, or Bentley GT cruiser is the
best compromise/option--I think.
As for 845s based amps, currently my bet is high on Jadis SE845NEC over others. But
wait.. this is ARC's thread! :)
Cheers,
