WHICH ARC LINESTAGE TO REPLACE LS-15?



Hi,

I'm looking to upgrade my LS-15 to one of the following linestages:

LS-5 Mk III, LS-16 Mk I, LS-25 Mk I, Reference One, Reference Two Mk I

How do you compare those against each other? Please share your experience if you owned any of them...

I like the sound of 6922 tubes... How does it compare to the sound of 6H30 in the more recent LS-16 Mk II, LS-25 Mk II, Reference Two Mk II?

My system as follows:

Wadia 830
ARC LS-15
ARC VT-130SE
Sonus Faber Cremona
MIT Shotgun S3 IC & SC

I listen mostly to Classical Baroque and Jazz instrumental & vocals

Thanks for your advices!

The LS16 is not going to do much over what you have right now.

I have said so much on this site on the LS5 so I will simply say that with the VT130 for which I also owned and ran with, the LS5 was an awesome match....especially with the VT130 loaded up with KT88's. The LS5 does come with an optional remote for volume and this works mighty fine.

As for the LS5 having only balanced ins/outs, since your VT130 only has balanced inputs, this is not an issue. And just about every source out there today has XLR outputs....some of which are truly balanced. I liked the LS5's all-balanced topology since it did not have all those klugey circuits to convert to/from single-ended which results in sonic degradation.

If you are seeking something in the $1800-2300 range, the LS5 II/III has no peers IMO. The Ref1 is way over priced and for all the LS5 owners I knew that also auditioned the Ref1, we all kept our LS5 II's and III's.

I did not hear the Ref 2 Mk I but this was the last ARC line stage to use the 6922 and this just may be worth hunting down. And then look into dropping Mullard 6922 tubes in this. Wow, could be mighty good! Whatever you do, if you end up with a 6922 tube-based model, donate the Sovtek tubes to charity. They put a most un-natural bite and fatigue to the sound. And no amount of circuit design or correction can resolve this whether it is an ARC, CAT, Aesthetix, etc., product.

Thanks to all for your feedback

Based on your recommendations I'm narrowing down to LS5 Mk III, LS25 Mk I and Ref Two Mk I

I'm looking for 240V unit... but does anyone have experience in modifying a US unit from 110V to 240V?
Joel_hifi, I strongly suggest that you talk to Leonard at ARC about any 110V to 22V modifications. As ARC would perform any such mods, they are the prime source of info on it, if the mod were possible at all. Phone ARC at: 763. 577. 9700
A few years ago, I sold my LS5 II to an A'gon member in the UK. Initially he investigated having such a unit modified through ARC but ARC told him he had to go through the UK distributor for such rework. The resultant cost was approaching a ridiculous $1k through the distributor as everyone always wants a large piece of the pie. Rather than play this game, he asked me if we could do this in the US before I shipped it. And with me being only minutes from the ARC facility, we did just that. The cost was $225 to purchase and have a different (220V) power transformer installed at the ARC factory. And it was done that day. Nice and easy.

So as I understand it, ARC is very good when the business is USA to USA. But outside of the USA, you're pretty much stuck with dealing with the overseas distributor.

And yes, Leonard is very helpful and friendly with such issues.

I recently purchased one which came with reference level modification from the Great Northern Sounds (GNSC). It also came with a quad of Siemens Falcon 6922s recommanded by Steve Huntley of GNSC. (The previous owner went all out with the mods) The LS-25 replaced the LS-2B Mk II that had been in my system for almost 8 years. In short, I was very impressed with the overall improvement. (I did not know my Thiel 3.6 was capable to produce that kind of bass and soundstage, and I had them for 10 years) The other day, we did a shootout between my modded LS-25 and a Sonic Frontier Line 3 SE. Everyone preferred the Line 3 slightly over the modded LS-25. But when I took out the Siemens and inserted a quad of Amperex white label USN-CEP 7308s, it was like we were listening to a different linestage! All 4 votes went to the LS-25 with Amperex tubes. The Amperex simply embarrased the Siemens! (I had tested those tubes on my TV7D/U tube tester when I first received the unit, so I know they are still OK)

Regarding the GNSC mod, I have been wanting to do a shootout with a stock LS-25 MkI to see how good the GNSC mods are. I sent out an invitation on Audio Asylum but got no response. I guess there aren't too many of them out here in the San Francisco Bay Area...

My next challange will be against a Ref 2 Mk I and a Ref 2 Mk II.

As for modifying ARC products from 110V to 240V, I have heard that it is a closely guarded secret and that ARC does not like to do that. Do a search on here and AA, I think there was a thread a few weeks ago discussing about that.
