Line Stage battle: ARC LS26 vs Aesthetix Calypso


Dear Members, This is my first post on Audiogon & I would like to thank Audiogon and it's members for a fantastic community of dedicated fans of high end audio. For my first post, I thought I'd pick two exceptional line stage pre-amps costing roughly the same, yet created along very different design philosophies and pose the question - In a no-holds barred cage match between the two, which pre comes out the winner?

Audphile1, thanks for your considered and interesting reply! I've also read the ARC LS26 is an exceptional pre at it's pricepoint & is very close to the Ref3, and that is a big statement given the Ref3's ticket price.

I appreciate your comments about ARC's reliability, as I had read one review which suggested otherwise (but only one).

Re: the Calypso, i've also noticed a lot of owners switching tubes after purchasing that pre, yet I haven't heard that kind of stampede to mod the LS26 whatsoever, so that sais something about how good it is straight out of the box.

The power amps which I will be buying to bi-amp my speakers have high current, so the LS26's adjustable gain would certainly be an advantage. I also like the LS26's display & the fact it displays tube hours as well. It also looks fantastic with that mean-looking aluminium faceplate & handles!

I'm planning a system upgrade which will include a pair of Infinity Ren 90's, so i'll be bi-amping them with high current Benchmark dual mono power amps & need a smooth, open & clean sounding pre which will exploit the maximum potential from the Ren's planar drivers. My source is a JVC XL-Z1050 Class C transport connected via a Nordost 'Silver Shadow' cable to a Vimak DS-1800 Mk2 Dac. Given that company, the choice of pre will be critical. One thing is for sure, the LS26 will definitely be on the rack when I start auditioning pre's!
Anything can break. But in case of preamps, reliability issues with ARC linestages are most likely limited to the units that have tubed power supply - REF2, REF2MkII, REF3. That's probably what you have read. You have to watch out for the power supply tubes and replace them on time. There is definitely a potential that a failed PS tube can take out a resistor, etc. So that would definitely be possible.

If you want a tube preamp that you won't have to worry about tube rolling or mods, LS-26 is the way to go. If you think you would like to experiment with tube rolling, then the 6H30 based pre such as LS-26 iswn't for you, because there is no tube rolling the 6H30s. But the advantage is that the tube lasts longer, and you won't get on a merry go round of tube rolling, which can be fun and frustrating and expensive all at the same time.

Good luck assembling a new system. It is fun!
Thanks for your comments Audphile, I am actually off in a different direction now. I have been blown away by the Cary SLP 05 tube pre! It just gets everything right. A pre-amp which sounds like a TRUE all tube pre-amp but without any of the typical trade offs like tube noise, lack of bass control, too warm/tubey (at one extreme), too dry & clinical (at the other), reliablity issues etc. Twin box design for low noise characteristics, fully balanced design, cool looking Mac-like meters & 8 exposed warm, glowing tubes to make your heart smile. And you have Cary's legendary back up service behind it. I know that ulitimately, hifi is about personal choice & what sounds good to YOU, but i've heard a number of people tell me this is one of the best pre-amps in the world & sounds better than the ARC Ref 3, that's a big statement. A'goner Rbirke's review from Feb '06 is a great read by the way, I am salivating over this baby!
You won't be wrong on Cary SLP-05, it is absolutely a remarkable pre. Tube rolling is fun, but the EH stock tubes are not bad at all.
I agree about the Cary, I tied the 05, but could not afford it bought the SLP-03 w/ 12au7 tubes tube rolled to NOS and have no regrets, a bargain for the money at 3K, I like the single box design, completly dual mono construction, dead quiet, works great w/ my Wyred4Sound monos
