Ah! A good music recommendation, I will get that.
I never compared the Atma-sphere preamp with the LSA as I use it with the Atma amps in all balanced connection, so I jave not been able to compare them with the same amp.
I use the LSA with the Music Reference RM10 (summer) and RM 9 Special Edition (Fall), both amps single-ended. I went through a series of preamps, most recently the CAT SL1 Ultimate, Lamm LL2, and Joule LA150 Signature Edition. Of these, the Joule was the one I liked most and could live with it forever, but I decided to try the LSA just to see what it might do versus one of the best sounding active tube linestages I have owned. I kep going back and forth for a few months, and without too much analysis, I simply felt I liked the LSA better, certainly as much as the $7,000 Joule - seemed silly to keep both with that kind of price differential and since I only have one source, low capacitance cable (Cardas GR), and both MR amps were designed by Roger Modjeski speciofcally to be passive friendly (High input impedance, high sensitvity <1v) I figured that while an active will sound better with a wide range of sources, amps, and speakers, my particular system is really passive optimized and that under those circumstances a passive should be better at passing the signal undamged from source to amp.
The LSA is very, very quiet, seems to be very well balanced from lows to highs, has a very wide and deep sounstage with recordings that have wide and deep sounstages - soundstaging with this preamp really is a reflection of the recording and not a constant attribute, and imgaging and localization is very precise and unwavering, and instruments seem to have their naturural size and instrumental bloom. I also notice that music can be played louder without unpleasant shout that can occur with some systems.
Within my system, there is really a hairsplitting comparison with the CAT, Lamm, and Joule - they are all exceptional pieces of equipment and enjoyed all of them. There is not however a hairsplitting difference in price - which is why I love the LSA, it can give audiophiles without deep pockets SOTA sound if they pick their sources, cables, and amps carefully/properly. Or, if you have the money, you can buy one of these great linestages and have a great system too, without worrying much about system matching.
Arthur Salvatore says that if your system sounds better with an active linestage, your system needs an active linestage - but if you don't need one, a passive is the way to go. I think this in part explains why some folks swear by passives, and others say they much prefer actives; I suspect where you fall depends on your system as a whole, and not necessarily a reflection the inherent qualities of either approach - why as they say wisely, your milage may vary.
