OK, I want it! I want it! I want it!
It's time to start throwing those hissy fit tantrums with my wife--who by the way could not care less about my righteous audio yearnings!
Jokes asides, the specs sound very impressive. At least on the page referred, the price seems the same 10K as Ref 2 Mk.2: I hope this is real and not an oversight from the site's owner.
Oh well, companies that have strong market presence with products with unique personalities will always be a little controversial and become the favorite topic of animated discussions. On the other hand, I hope we will be able to keep the bulk of the postings on this thread roughly on topic. I'd like to invite anyone who is visiting CES to comment on the Ref 3, if they have already seen it.
I have just called Audio Research. I have confirmation that Ref 3's price is the same as the older Ref 2 Mk.2. This is welcome news inddeed, as I was fearing/expecting/dreading a higher price. The product is being shown in Vegas at CES as I write. I will receive a blurb in the mail during the next couple of days about it. I will OCR it and post salient passages to the thread as soon as I receive it.
I ordered a new REF 2 just before the new year, matter of fact, I didn´t know (neither my local shop) that the REF 3 was available, so originally I ordered a REF 2 and only early this week, when the shipment was suppoused to leave the States, we found out of the new REF 3. It´s on its way now, expected arrival by saturday next week toghether with a Krell 700 cx...I cannot wait!
Now, I have a question: I received the specs by fax yesterday from AR (incredible service, one call and 2 minutes later, 3 pages on my machine) and can see that there are several differences on the specs when compared to the REF 2. Specifically, the ones that rings me a bell are gain (lower than ref 2), higher impedance output than the ref 2. Can anyone enlighten me with what does these differences mean? I can post the specs here if needed, yesterday were not listed on the ARC Data Base.
The lower gain is probably no big deal, but the higher output impedance might make a difference if you decided to pair the preamp with a solid state power amp. The Ref 2 has an output impedance of 400 ohms and ARC suggests a minimum of 20k ohms input impedance for a power amp. ( 50/1 ratio) In balanced mode Pass Labs amps are 22k and some manufacturers offer amps below this figure. Most tube amps , including ARC come in at about 100k . In any event enjoy your new treasure.
Hi Jeff, thanks for the clarification. Currently, I have my LS25MK2 mated to a Krell FPB300c. The new Ref 3 will be mated with the 700cx, so I guess it will be no trouble matching those 2? The specs for the REF3 are:
freq. response: 0.2 Hz to 200 Khz
Gain: 11.6 balanced (18db on ref2), 5.6 db SE (12bd on ref2)
impedance: 600 ohm balanced (400 ohm on ref 2)
max input: 20 v rms max (balanced) (14v on ref 2)
output: 2v rms into 200k ohm (2 v into 100k ohm on ref2)
noise: 2.7 uV (20 uV on ref 2)
tubes: 4x 6H30P (plus -1 each- 6L6GC and 6H30P in power supply)
Does anybody sees what these changes suggests?
Thanks, brgds, Marcelo
Marcello, if I understand things correctly, and the Ref 3 has an output impedance of 600 Ohms on the balanced outputs, this change makes the device meet the standard for balanced output impedance. I spoke to a friend of mine who is a pass lab dealer. He told me that the ratio between pre output impedance and amp input impedance need be only 1 to 10 for good results. So for example, as the Ref 3 has 600 Ohm output impedance, and the new Pass Labs X600.5 amps I am interested in have an input impedance of 22K Ohms, the two should, at least in theory, work well together, as the ratio is 1/30. Needless to say, my knowledge of the subject is rudimentary at best.
Hi Guido, mi knowledge is also very very limited, here I am, talking about impedances and gains while I have not really a clue how this 2 work toghether...
Anyway, I will be using the REF3 with a FPB700cx that I ordered to arrive toghether, and I can tell you that the Krell has an impedance input of 100 Kohms and the input sensitivity is almost 4v. If we consider that the AR pulls out 4v when having a 2 v input (this considering the 6 db gain on SE of the REF3 and considering, IF I´M NOT MISTAKEN that the 6 db gain means doubling the voltage), there should not be any problems...I guess...what a mess...
Using your formula of minimum 1:10 ratio, do I understand correctly that with a 600ohm output (REF3) and a 100kohm input (Krell) we have something like 1/160?
Expected delivery at my place is late this week (maybe as late as friday or even saturday) but this will be confirmed to me tomorrow or tuesday.
Word is that both units should be in Spain by now....
I can't wait, I´ve been going around in circles thinking of the Ref 2 for a long time (well, not that long, I´ve only had the LS25MK2 for 1 year...), as well as upgrading the Krell 300c.
Hard to know at this stage, I doubt many (if any) have had the chance to listen to either one.
However, I´ve had the KCT at home and was sent back, in my system, I liked a lot better the AR.
Anyhow, 35k$ would probably result in 50k$ in Europe...out of my league. I´d rather spend the 50k in a pair of Statements...
arrghhhh....just learned today that the Ref3 AND the Krell were not shipped yet from the factory...this means minimum another week or so. I have not the details as for why the delay, but could imagine neither ARC nor Krell had a 240v unit ready to go...
Oh well, I´ll concentrate finding a new cart to upgrade my Frog Gold MKII...any ideas?
As the Audio Research web site has not been updated with information on the new Ref 3 linestage, I thought of pasting here the OCRed content of the entire blurb on the device that I have recently received from Audio Research. So, here it goes. . .

Introducing the REFERENCE 3
Introduced more than five and a half years ago, the REF2 has received a continuous stream of accolades from around the world. True to its name, it has become the reference line-stage preamplifier, purchased new by a thousand music lovers and coveted by thousands more. With the MKII version four years old, it is time to push the performance envelope once again. We are proud to introduce the new REFERENCE 3, with a retail price of US$9,995.00.
"Breakthrough" is an overused term, but it is the most fitting word to describe the REF3. As you can probably imagine, it is difficult to write about a new product like this without sounding cliched, but the REF3 is so good that it is startling when you hear it in your system. How is its presentation superior to the great products that have preceded it? Simply, in every way. The REF3 is more musically transparent. It presents a soundstage that makes everything else sound one-dimensional. There is pinpoint focus of voices and instruments. The deep, powerful bass is fast, articulate, and controlled. It posesses a dynamic swing that is breathtaking. And, most importantly, there is a directness and immediacy that connects the listener with the performance. The results are simply thrilling.
Externally the same dimensions as its predecessors, the REF3 is new inside and out. The front panel marries the classic Audio Research look with a modern display and intuitive controls that will be appreciated. In the middle of the panel is a large display which can show the volume level (numerically and via line graph), input, and operating status (including BAL/SE, Mute, Mono, and Phase). Flanking the display are two knobs which control volume and input. Under the display, in place of the toggles, are four soft touch switches controlling Power, Processor input, BAL/SE, and Mute. The new remote controls all front panel functions plus the balance control, and also a display readout of the number of operating hours the vacuum tubes have been in service! It will be easy to integrate the REF3 with system controllers from companies like Crestron or AMX. Inputs are direct access, and there are discreet codes for power on/off, processor on/off, etc.
The rear panel is the same as the REF2 except for the deletion of the tape monitor input. The REF3 does not have the ability to listen to one source while taping another. Also, the IEC connector for the removable power cord has changed from 15A to 20A.
The remarkable level of performance has been achieved with all new audio and power supply circuits. There are four new circuit boards and two new transformers. The new audio circuit is pure tube, Class-A, with zero feedback, utilizing a total of four long-life 6H30 twin triodes. FETs are
P.2 REFERENCE 3 introduction
used for constant-current sources, and the analog circutry uses a long-tailed pair input stage to provide the same performance in either single-ended or balanced operation. Total gain is 12dB balanced, 6dB single-ended. The hybrid power supply has over 50% greater energy storage than its predecessors, greatly contributing to its tremendous dynamic capability. There are other improvements which can be seen on the bench. Bandwidth has increased from 60kHz to 200kHz; noise has been reduced by 12dB; headroom is much higher, with the maximum input increased to 20 V balanced, and distortion has been lowered by 40%. The advancements of the REF 3 are both audible and measurable. As you would expect, older REF preamps cannot be updated to the REF3.
It will be easy to hear and see how the REF3 extends the boundaries of preamplifier design. With its great build quality, versatility and the ability to musically transform every system, the REF3 also represents great value. Building upon the foundation of its famed predecessors, the REF3 will be a resounding success. Call your Audio Research dealer to schedule a personal audition.

I traded my Ref 2 Mk II (which I still think is an awesome product that I would be proud to own) for the Ref 3 several weeks ago. I had the chance to a/b them for about two hours in my home on my system using an sacd front end before I wrote the check. I thought that the Ref 3 was quieter, had greater dynamic range, and was more transparent. Also, in comparison, the Ref 2, while throwing a huge soundstage, sounded a little as if it had been processed through a phase shifter. The 3 did not have as big a soundstage, but now that I have racked up about 130 hours on the unit, that is coming along. Regarding the noise floor and dynamics, the Ref 3 was superior to the point that I had difficulty setting the two pre-amps at the same perceived volume. The difference was not unlike the blackness between notes on good sacd compared to redbook. Also, the 3 is not quite as warm and bloomy, but is tighter in the bass and cleaner top to bottom.
Although this sounds a little bit like the ARC promo, it is really my own thoughts developed primarily during the a/b session. Hope this was helpful to you. You really cannot go wrong with either pre-amp; both are great.
Rom, the observation of the Ref 2 sounding almost slightly phase-shifted and bloomy is right on. I am delighted that the minor shortcoming has been addressed in the Ref 3. How many hours have you racked up on the Ref 3 break-in this far? Are you using the stock power chord or an aftermarket powerchord? Thanks, Guido
Yesterday, the tube hours counter read in the 130s; my rig is off right now.
I did the a/b comparisons using the stock cords on both units.
The Ref 3 comes with a hefty cord with a 20 amp IEC. I plan to eventually try out some commercial cords (probably Shunyata, others), as well as homemades made from twisted solid core wire shielded with tin foil. The sound is good enough that I have not felt compelled to mess with it yet.
I think you are really going to like the Ref 3. To my ears it does not cast a soundstage via the phasey sound you mentioned at all; it is gone. Rather, the sound is extremely focused, clean, and transparent. The soundstage you get is more like what is on the recording, but not necessarily as "spread out" as on the Ref 2 (at least not at this stage of break-in). The Ref 3 is really quite different sounding than the 2 but is still "beautiful" and natural, as opposed to cold and mechanical.
To perhaps help you put my comments in context, my current system is:
ARC Ref 3
ARC VT-100 mk iii
Audioquest Anaconda ICs
I'm sure I'll get around to messing with my digital front end eventually. I wish that we would see some more killer SACD players, as I have invested a fair amount in SACD software and generally like what I hear.
I did not find sheen or glare to be a problem with the 2. I do not really recall a difference in the two preamps in this regard. Again, there is a family resemblance to the sound between the 2 and 3, so this is something you will need to check out for yourself.
I would be interested to hear the opinions of others who have tried the 3 with top flight sacd front ends.
Rom, I detected the slight 'sheen' when auditioning the Ref 2Mk. 2 next to a Boulder 1012 preamp, which seemed at the time to have a slightly warmer more musical sound, still maintaining top/bottom extension. The preamps were driving a Rowland 3.02, and a pair of Utopia (perhaps Altos). By comparison the Ref 2 Mk. 2 sounded just slightly hard. In complete honesty though, I auditioned the Ref 2 Mk. 2 another time on a different system, driving ARC VT200 and Maggie 3.6 speakers, and found it marvellous.
In both cases, the Ref 2 was driven by an ARC CD-3 Mk. 3.
to my thought he Ref 3 is quieter, had greater dynamic range, and is more transparent. the noise floor is very low . the sound is extremely focused, clean, and transparent. the soundstage dimensions as with the former Ref 2 wide. tight bass and clean top. very good low level detail information. bass articuliation is in a class for itself. very holographic.
Hi all, I´ve just unpacked my REF 3, finally home!
Right out of the box, dead cold, hand to hand with the LS25MKII, it was a revelation in terms of sheer bass response without loosing the top end.
After 2 hours continuos operation, suddenly it changed and sounded like the scene was grouped in the middle (no, I was not in mono mode ;-) ) and harsher than the 25...one hour later (now we are at the 3rd hour) and it came back stronger than ever.
A friend of mine who knows well my setup drove to my house with his `reference´ recordings and was amazed at the clear sound, but most of all, dynamics and bass response.
Too early to say anything else, need what...100 hours? (no mention about burn in time as with the CD3).
Anyway, it is different and certainly an improvement to the 25 (sure, what else..). One of my worries about the lower gain (down from 9 db to 6 db SE on the phono section) is gone. There is enough there to drive the Krell 700cx with the Colibri at the other end (0.3 mV) at very loud levels. Back to the listening session now...bye
