Too exclusive/expensive in Australia due to currency difference. Sovtek valves

After finally finding a secondhand ME850 power amplifier last year ( this was always the power amp I aspired to buy one day. $6000AUS when new, no longer in production ) I connected this to my existing Audiolab 8000Q Pre-amp. It really impressed me with it's added control over my Hybrid Ribbon speakers and a very slight increase in soundstage. The Audiolab is a great solid state pre-amp but now I was itching for improved soundstage seeing I had plenty of power/control on tap. I took a gamble and purchased the Chinese made Classic No. 9.0 Tube pre-amp and the soundstage opened up 2 fold over the Audiolab, but the gain was too much which meant I could never have the volume knob past the 10 o'clock mark. I swapped tubes and used attenuators and as I fixed one issue it shifted to something else. Although it was a nice pre-amp ( a little bright ) the mis-match between it and my ME850 power amp was driving me to distraction. I kept my eyes & ears out for other possibilities and as luck would have it, I found a secondhand ARC LS-15 advertised on a Hi Fi shop's website that was located interstate. I had dealt with them a couple of years prior, so no problem in getting them to send it to me via road freight and they even accepted my Classic No. 9.0 pre-amp as part trade in. What can I say that hasn't already been covered by eveyone before me. This pre-amp is just GREAT ! Beautiful soundstage and very unfatiguing so you can listen for hours and get seduced by the music rather than "playing with your Hi Fi" ! I have to admit that the bass extension was considerably more than I'm used to but also not as tight when compared with my Audiolab 8000Q pre-amp. But considering one is tube and the other solid state quite understandable. I did find a couple of Mike Oldfield's later CDs didn't fair too well when played through this pre-amp. I'm willing to make an educated guess that it may be due to the fact that most of Mike's work is done on computer/synth and some tracks may be slightly "over produced". After scanning through the various comments from other owners, I decided to replace all the included Sovtek 6922 tubes with some NOS JAN Philips ones and guess what ? I can now listen to those Mike Oldfield CDs again without the bass blurring out the highs/mids & soundstage. This pre-amp really shines with Jazz & Vocal material and breathes air through those recordings with effortless ease. I have found since getting this pre-amp I'm staying up later into the night listening to my music, especially well recorded vocals. The imaging and soundstage is expansive and seductive to say the least. The previous owner of this little number had it for 9yrs before upgrading to a newer ARC pre and seeing I just stocked up on NOS 6922 tubes, I intend to keep it for many years to come ! If you can find a nice pre-loved LS-15, grab it !

This is a wonderful preamp. Soundstage is excellent. Each instrument is extremely well defined. High end is a bit rolled off but certainly not shy. Overall sound is very warm and pleasing. Bottom end is very good but will seem lacking on recordings that are bass shy. Play a recording with an extended bottom end and this preamp will shine however it is not very forgiving on recordings that are a lacking on the bottom end. In other words, if it's not on the recording it's not the preamp...it's the recording. Since this is my first tube preamp the high end and bottom end may be very charactaristic of tube preamps. Overall this is an excellent preamp definitely worth giving a listen to. This is a keeper.

Comes with Sovtech-lack of "Slam"

This preamp is a great piece of equipment when the Sovtech are replaced by any other 6922's (valvo in my case). The musical details are amazing compare to a CJ PV-10A & an ARC LS-2 (which are very good preamp BTW). For Jazz,singners & classical lovers this is one of the pre you should consider.For big orchestra or Rock I find the LS-15 with a lack of "slam" when compare to the LS-2. I am running it in balanced mode with an ARC VT_100;I also try it with my Odissey Stratos (SS).With the VT-100 it is an amazing combo;with the Odissey it was less magic. The soundstage is very good and the instruments are well located;same thing for the depht.This preamp is also very dynamic and,with its quality for the details,may make you realyse what you were missing before.In my case it was a big revelation;even with the LS-2 (the CJ PV-10A is far beyound the LS-2).

This is truly a great preamp. I recently traded my Sonic Frontiers Line 2 for this an d am completely satisfied. The Line 2 is truly overrated as it has a lifeless, cold and steely sound. Tizzy treble is augmented by a bottom end that is too tight. Nothing sounded real. The LS15 has a wonderful top end, a very neutral midrange but a minor problem in the bottom end which is typical with tube preamps. This problem is very minor and not noticed with my Classe 400 amplifier. This in a nutshell is a great preamp where one would be either foolish or swayed by the product of the month in Stereophile magazine to need anything more.

I bought this unit used in the pawn shop for $900. I have been in pursuit of a tube pre-amp for quite some time. I had either Audio Research or Audible Illusions in mind. A couple of weeks I went to the pawn shop and lo and behold there it was! The unit would be in mint condition except for a nasty scratch on one of the handles! Thirty five dollars will remedy that problem along with $100 for the remote that they didn''t have. I don''t know what kind of tubes the unit has but I plan to experiment when I learn a little more about the tubes. The detail and sound staging is everything that I expected, and then some. I am using an Aragon 4004MKII amp, which seems to be a great match with the AR. I purchased the Aragon about the same time that I bought the amp, and when I got it home it sounded terrible! I had a pair of Monster Cables that caused my ears to fatigue after 5 minutes of listening! I have some cheap "wires" that I am using now. My next project is to get a 15 ft. pair of Transparent or Mit cables. Even now, with the crap that I have for wires, the unit still sounds sweet and detailed. I am very happy with the LS15 and it has found a permanent home here. I would like to upgrade to the Aragon 8008bb and a Levinson #39 transport. I am using a Cal Audio Delta transport, Meridian DAC, KEF Q60 speakers, Aragon 4004MKII, and of course the LS15 with the Mickey Mouse wire set.

I upgraded to Thiel 3.6s. As a result, I could not live with my Adcom preamp. The LS-15 created a sound staging I never thought possible. It also lessened the screamy sounds of my ADCOM power amp. Caution to all who purchase Thiels, they are very revealing. I also enjoy hearing high end and the ARC peamp does fine in that area as well. I highly recommend they unit.

The LS-15 is the finest preamplifier I've had in my system. It replaced the LS-2 MK II. It is a totally different animal. Very open, detailed, and wonderful bass response. LS-15 owners who have not upgraded to the new Infini Caps are missing all the fun. I've heard the Ref One and the LS-15 is not far behind. NOTE: ARC PH-3 Special Edition is an upgrade from the original PH-3 that is a must have for all PH-3 owners.

what more can i add, this pre-amp is so good that anyone who listens to it had better be ready to part with 3 grand. turning on the LS-15 is simply a way of inviting performers into your listening room, the dynamics, the resolution, the soundstaging are all superior to damn near everything else out there. in fact, the LS-15 runs a close second to ARC's top of the line REF-1 pre-amp from which it was derived. considered that a REF-1 will set you back 8500 clams the LS-15 is a bargain. sure the addition of a PH-3 to handle phono inputs is another 1500, but the combination is incredible. i hear that the PH-3 special edition at 2500 is even better. i've heard a lot of stuff but ARC's current line-up is within whispering distance of the very best, at any price.

I compared the LS15 to several Classe preamps and to the solid state ARC LS9. I decided to purchase the LS15 for three reasons:
1. Coherence of Sound - this preamp was the least "hi-fi"sounding unit. No particular frequency stood out. The music seemed to flow more naturally.
2. Detail - instruments sounded more lifelike. As an example, the shimmer of a cymbal sounded so real - the decay was not distorted or clouded as on some other preamps.
3. Features - balanced inputs and outputs; remote controlled.

The new Classe preamp (I don't remember the model number, but it was a new mode above model 35) was excellent also, but had an overly rich bass presentation in my opinion. But it was fun to listen to.
