ARC Ref3 or McIntosh C2300/2500

Can anyone comment on their actual experiences with these two pre amps?
I am considering an upgrade to my Audio Research LS26 and these are the ones I am considering. Both priced similarly on the used market, the Mac offers more features such as Phono and DAC (C2500) which is useful to me. But most important is how they sound. What I am looking for is more the "magic" tube midrange sound (which the LS26 does not have) as well as the wide and deep soundstage that I do have.
Just to compare, I put in a older VTL 2.5 pre amp and the midrange was much more to my liking than that of the ARC which sounded a bit "sterile" and "analytical" as the reviewers say. But the VTL did not have the wide soundstage nor quite as deep, fast, and top as the ARC.
Other gear :
McIntosh MC402 amp with Wilson WP6 speakers
ARC CD3, ARC PH5, VPI Traveler, Benchmark DAC. Transparent cables.
I listen to all sources, mostly classic rock, Jazz,
Thank you
Based on your stated preferences, I believe you would find the ARC Ref3 to be the better choice.
The Ref3 in a heartbeat.
No contest for me. REF3.

The McIntosh unit was nice but the REF3 was at an entirely new level.

You already have a PH5 phono unit which is not bad at all. Also, you have a Benchmark DAC. Although I'm not familiar with this DAC, I wouldn't get the Mac solely because it has the phono and DAC built in. That tends to lower the quality of the reproduction of the sound.

Separates usually make for a better system.

Another thing, is how old are the tubes in the REF3? If they are close to the useful life, the sound may be compromised.

With new tubes, not much comes close.

The REF3 and the REF5 however are so close in sound and quality that I would not upgrade to a REF5. However, the REF5SE on the other hand is entirely different. A really nice unit noticeably better in sound (enough to justify upgrading) than the REF3.

In my opinion, the Mac unit isn't on the same level.

Vdosc, Both of these companies make great gear. To add another point of view here, I have the C2500 that I use with a Levinson 331 amp, Transparent cables throughout and Wilson Sophia 3s. Music is streamed from the NAD Bluos system. The Hybrid system works beautifully for me. The Mac has added musicality to the Levinsons precision. Imaging is crisp and listening is non fatiguing. I respect both the Mac and ARC Brands and had a similar choice not long ago. I chose the Mac because it is multifunctional and its' connectivity really future proofs my pre-amp for a long time. If you use the internal DAC, it's actually quite excellent. Believe me, no rap on ARC. If I went that route, I'm sure I'd be singing its praises. There's no wrong choice here. Find a dealer that carries them both and take a listen. How bad can a Mac tube pre-amp with an awesome Mac ss amp be? Best of luck and have fun in your quest.
I have to chime in here as I am a McIntosh guy. I have McIntosh amps and have had a number of McIntosh amps and Pre-amp and Pre-Pros. I currently have a LS26 and would say the REF3 without question. As much as I wanted to by a C2300 when I bought my LS26, it took a moment of self control and honesty to depart from an emotional attachment.
Yes the REF3 will bring you much more musical pleasure.
The Ref 3 is a great preamp, (and I agree with Minor1 about the Ref 5 & Ref 5SE). However, IMHO, it does not really have that classic tube midrange sound that you said you want. It uses the 6H30P tubes, which are very neutral sounding, and very quiet, but don't really have that classic tube midrange. (Personally I like it, as I like a very neutral sound myself.)

I recommend that you check out some of the VAC preamps, (there are a few for sale here on Audiogon). The VAC house sound has a bit more of the tube midrange that you said you want, at least IMHO.

Good luck in your search.
A number of years ago, I switched from Mac C1000 3 piece (tube,ss, ps) pre to Ref 5 and felt the Ref 5 crushed it. This caused me to unload my Mac amp for an ARC amp which was of equal or greater importance to the overall gains in my SQ. The only area where Mac combo was better than the ARC combo was on impact in the very low end. But, the bass on the Mac was also somewhat diffuse and not nearly as tight and well defined as the ARC. All in all---no contest. Not the exact comparison you seek but I think instructive of the house sound of each. Ref 3 will be more refined than LS26 and tube magic will be there in the midrange, but more transparent than Mac.
Hate to tell you cause I know your amp well, but I highly recommend going all ARC or all Mac. For a time, I had ARC Ref 5 and Mac amp which I thought was the worst of both worlds. An all Mac system gives you smooth, rounded, burnished and pleasing but not very transparent sound. Never bad, never great. An all ARC system brings huge soundstage, great color texture and bloom. Rarely bad (recording has to be awful) but often sublime.
I'm not surprised by your VTL / Mac experience as VTL is closer to Mac sound so this would not produce the worst of both worlds. Any chance you can try an ARC amp in your system to see what I mean?
By the way, all of my experimenting with ARC and Mac (also VTL, BAT and Lamm) came when I had Watt Puppy 7s.
I agree with the recommendation for the Ref 3. All I would add, is that the LS27 is a definite step up on the Ref 3, having auditioned both together and both can be found second hand.

Another thought if you are looking for a "tube" midrange, is Conrad Johnson. I used a CJ 17LS for years and just loved it. You only get Phono, not XLR outputs of course.
I agree on all counts with Kurt_tank. If you want a sound more like the VTL in the midrange, I'd suggest VAC or, if you want an ARC product, a well-maintained LS5, if you can find one.

having heard all pre-amps plus the ARC Ref5 SE models in your query, I can very strongly suggest (w/o hesitation) the ARC Ref 5SE. This is the one you want! Save your time and money on the rest. Oddly enough I felt the Ref5 SE sounded best when mated w/ a Bryston power amp on Wilson loudspeakers. Keep me posted & Happy Listening!
This is all great information! If I could afford to, I would have two or three different pre-amps (or complete systems) here at one time to really compare.
Although I would never get anything else done ;) I don't have any good dealers near me that cary either brand much less both to try and compare, so I must buy to try. Also I still have my older ARC VT100MKII power amp, which is not bad at all, however I like the Mac 402 better with the Wilson WP6. It may not sound as "warm" in the mids as the ARC but It has gobs of clean power , which translate to better attack, tighter bass, also there seems to be better imaging, and decay on instruments and reverb, etc. I have not had a ARC REF amp in my system yet, and I am sure it would be great, but they are at this time not in the budget. Also I really like the look of the Mac!
I should ad that I am trying to keep my budget around $5K for this ,
hence my interest in REF 3 and or McIntosh C2500 range.
Thank you
You should be able to find a decent used REF3 for $5k. For that money, I don't think much comes close. This really is a very good pre-amp. Just make sure there is still life on the tubes. The REF 3 has a tube life counter that will tell you.

Can't speak about the MAC, but I used to own the Ref 3. Wow ... what a piece of kit.

I also agree with the comments above re the Ref 5. I moved up to the Ref 5, but was quite surprised that it was NOT in a different league as compared to the Ref 3. I since upgraded my Ref 5 to the SE and think the improvements are very noticeable.

So I vote for the Ref 3 ... or if you can find an LS 27, another good choice.

I happen to agree with the comments that ARC tube gear does not sound tubey. It is warm, neutral, open and very enjoyable. Some may call that analytical, but I think the use of terms is just quibbling about taste.

If your budget permits, I would think about upgrading your phono pre to the PH-7. Forget the PH-8. Not worth the bucks. Also, keep an eye peeled for a nice deal on a CD-5, which is the SS version of the Ref CD-8. I own the CD-8 which is a very nice CDP. The CD-5 and CD-8 both use the same Burr Brown DAC chip set.

But the bottom line is that either the Ref 5 or the LS 27 would make for a fine center to your rig.

We can talk about amps in another thread.


A further thought on ARC vs McIntosh in general. I have heard a lot of demos with ARC components vs McIntosh components. These are two great companies with loyal followers. My personal experience, however, has been that with the exception of some of the McIntosh tube gear, in most cases ARC performs in a whole different dimension than McIntosh. I love the McIntosh retro look and their pricing should put their products alongside the best out there, but folks, we're talking about a major league difference in what ARC components are capable of. I'm really not trying to trash Macs, but let's get real here. ARC has always been about pushing the boundaries of what is possible in high-end reproduction. McIntosh has never been taken seriously in the same way. This admission has been acknowledged even by many of the dealers who carry both lines (in their more truthful moments). Personally there are other reasons why I might own Macs, but not because I would expect them to be as resolving and tonally accurate as ARC products are and have been for a very long time.
I have the REF-3 and loving it. The time for me to upgrade preamps will be when ARC comes out with a new preamp that takes advantage of the technology found in their two-box 30 series. Don't know when that will be, but knowing ARC ... you know its going to happen.

And, I have the pH-8. It makes the PH7se that preceded it sound broken. Especially with these tubes:
During most of the 1970s I sold high end hifi equipment. I worked for two dealers, both McIntosh and one that also sold ARC. When I left the business it was with a full complement of ARC equipment for my own use. Today I own CJ, but still like the sound of ARC a lot and would be more than happy to own it again any time. With that said, the day is far off when ARC equipment would measure as well McIntosh. The fact is, when we say that ARC is our preference, what we are really saying is that we like the distortion that it adds, more than we like the distortion than McIntosh equipment adds. If we decide that ARC or any other tube gear is more tonally accurate, what we are really saying is that we find the inherent 2nd order harmonic distortion typical of tube gear to be preferable to the higher order harmonics that are more likely to be found in transistor stuff. I wish we could get away from the euphemisms and nonsensical poetry of the hifi press. When someone writes that one piece of gear is more "resolving" than another, that is meaningless. I expect a more sophisticated group here. Come people. Work with me on this.

think about a VTL 5.5 pre-amp and demo, if possible, prior to any purchase. Conrad Johnson (CJ) is another consideration. Keep me posted and Happy Listening!
