Default Sparkler S502i Smart Amp + 509U

Sparkler Audio Current mode smart amp

Sparkler Audio’s Smart amplifier with the smoothest and the most natural sound. Design of s502 was a painstaking fight against many elements that cause the degradation of the music signal quality on the minuscule levels to reproduce the natural depth and spread stress-free, "elegant" and "refined" sound.

s502 utilizes long life, high reliability reed switches with vacuum sealed ruthenium contacts that result in the smallest possible degradation of the sound quality.

S502u (current-mode): Inputs: 1 x Line, 2 x Line for current-mode

Output Power: 2 x 7 watt (8Ω)

Size: W300xH46xD100mm

Weight: 2.0kg

Input 1 ~ 2 current mode input

Dear Victor,

I wanted to write to let you know how pleased I am with my new Sparkler DAC (S504 Unison). I love the sound! It really makes my jazz and classical music collection come alive. Everything has a much fuller, richer sound versus the previous DAC I had been using. Some other reviewers have called it a “musical” sound and I agree – everything sounds much more lively with this DAC. I attended a live classical music concert yesterday and enjoyed the immediacy of the sound. This was what I had been missing with my previous DAC.

Besides the sound, the Sparkler S504 Unison DAC just looks cool. The handmade gold colored Japanese paper is quite distinctive. This DAC is very much a unique, handmade object, so rare in this age of mass production. I could have spent a lot more money on a so-called “prestige” brand DAC, but honestly this is much better – how many people have a Sparkler DAC?

I also ordered a full set of Sparkler interconnects, plus speaker wiring and a USB to SPDIF converter. All seem very well made and reasonably priced, and work great. Despite being custom made, the Sparkler products are priced well below other supposedly affordable brands.

I love that Mr. Tsukahara is basically running a one man shop, doing all the design and production by hand. He should be commended for his efforts.

And thank you for supporting him!

Best regards,

Jaylat
