This is all FWIW and I'll defer to anyone who's used both the Lightspeed and the SYS (I've used neither), but I'm betting the SYS would likely be a step down - at least in the short run, til you could get something better, but if there's anything better-sounding than the Lightspeed I can't imagine what that would be. The next best-sounding-for-the-money solution I know of would be Goldpoint attenuators (which I've used and have found to be highly transparent...on par, I believe, with the Lightspeed. Don't let anyone kid you though, the surface mount resistors used are ridiculously transparent and are the real thing, IMO). But, a stereo, single-ended Goldpoint is $159 without the knob, box or shipping. Other solutions might include Alps or whatnot, but none I've tried could hold a candle to Goldpoint or Lightspeed. If it were me and money was the overriding concern, I might think about the SYS for the moment and let it tide me over, unless the wait was expected to be unbearably long or whatever. But, if OTOH you happen to be more concerned with not wasting any of your hifi dollars by buying something twice, then I recommend maybe waiting until you're in a better buying position for a nice attenuator. But, after the Lightspeed, almost anything would likely be a step backward, except the Goldpoint...or possibly the DACT, but Goldpoint is what I know and they're in the USA. BTW, Arn is a super nice guy and can set you straight on how to choose the right impedance values with no worries.
As with all the passive attenuators, the shorter your IC's (6" or less - 3" is ideal) between attenuator and amp, the less there is of the usual sound penalty associated with passives (usually a loss of lower mid presence or decreased dynamics, or sometimes both).
Hopefully someone else can post with a lower-priced option here that I'm not aware of. Regards. John
