Is it really night and day

I just read that someone went from a ARC ref-5se to a Ref-6. They claim it is a night and day difference. For some reason I find that hard to believe. I can see there being a difference but night and day to me is an exaggeration. I'll tell you why I think this way. I had an ARC LS-25 for about 10 years and I always thought It was a good pre-amp. One day I got a bug up my ass and decided to upgrade to a LS-27. 

While I will agree the 27 is better than the 25 I would not say there is a night and day difference. Now that is a spread of about 10 years in a model. So of course you do expect some improvements and I have received those. 

Now going back to the Ref-5se. I think it has been around about 3 years. Now they have the Ref-6. So in 3 years there is a night and day difference between the 5Se and the 6 but after a 10 year period between the Ls-25 and the 27 there are a few minor differences. 

Sure it can.  His old Ref 5se was finished in black and his new Ref 6 is finished in silver. Sounds like night and day to me.  

I never thought of it that way. Thanks for the Insight.

Taters just try the damn things in your system then you can make an informed decision.
The REF6 is a completely different preamp from the REF5SE.

New chassis, new circuit board, new circuit design, larger power transformer, 2 more tubes, etc.

Why couldn't it be a "night and day" difference in sound?

Technology marches on...
Audiophiles tend to embellish.....A LOT! Haha.

It's always entertaining to read how product X Kills product Y.
Product Z makes product Y sound broken.
Product A totally smokes product Z.

and the record spins round and round..........
Embellish indeed!  I think I might have embellished once or twice - especially for the juicy rationalization that my money was well spent!

If you must have the latest, greatest ARC is a good one to get into....the are constantly improving world class products!  Aren't they???

A happy audiophile is not a shopping audiophile.

LOL...I like it! 

Then sadly I'm afraid I am not a happy audiophile as I am always looking at new gear. 

I've never experienced a night and day difference between any components, but my jaw has frequently hit the floor.
Do we have any review(s) on the Ref6 ?
I envy you guys who have experienced a night and day difference. For me, the best I've heard so far is from late morning to early-to-mid afternoon.

I have not seen any reviews yet. I am sure you will in the upcoming months.

Looking forward to it- taters.
Keep me posted & Happy Listening!
If you experience night and day differences, odds are you either have an active imagination, or one of the two units in testing is defective.

It all depends on what "night and day" means to most people. But, maybe if you replaced those Bose 301’s you’ve been using in your $100k system with upper end Magico’s....THAT I think would be night and day.;)
OP - Amen brother!!! 

The exaggerations have always had to be there for one of two reasons from what I can tell:

1. If the reviewers don't exaggerate how do they convince you to ditch that totally acceptable $5000 piece of gear to get a marginal at best or just lateral move for just $10,000. 


2.  You just spent $10,000 and you need to justify how this marginal if not latteral equipment upgrade is worth it. 

This isnt to say there arnt huge leaps, but in my experience from one generation to another do not huge night and day differences make. 
I agree with JMcGrogan. Since most people on this forum (me included) are constantly listening for ANY improvement to their systems, when we hear a marked improvement (ie 15 percent vs, say, 10 percent), we call that night and day. 

I think the comparison you gave would be night and day. But it is far from the comparison I gave.

I have often found that audiophiles drop off the "in" from the front when they use the word significant.
 Ihave had the pleasure of auditioning the ARC Ref3, Ref5 & Ref5 SE models.  The Ref6 is going to have to be very "special" to top the 5SE pre-amp.

I am not saying that the Ref-6 Isn't better than the Ref-5se. What I have a problem with is when they describe it as a night and day difference. 

I get get so sick of seeing these night and day references no matter what company they are talking about. It is Just a plain outright exaggeration.

Right On! taters.

I tend to agree that newer does not (always) equal better.
