GET GST INPUT
Ever wondered why speakers, amplifiers, projectors etc. come with a slightly heftier price tag in India compared to their overseas counterparts? Well, part of the answer lies in our country's Goods & Services Tax (GST).
But here's the kicker: Don't let that GST input slip through your fingers! Especially when some of the products we supply carry a GST rate of 18% and 28%.
At AVStore, we provide you with a GST compliant invoice for every purchase.
Simply put in your GST number during the checkout to avail an offset.

The E-800S is Accuphase’s flagship model that incorporates the full breadth of Accuphase's accumulated knowledge on integrated amplifiers. The preamplifier section incorporates a Balanced AAVA type volume control, while the power amp stage relies on an instrumentation amplifier principle and six-fold parallel push-pull configuration using power MOS-FETs driven in Class A, driving any loudspeakers to higher dimensions of sound. Enjoy the blissful acoustic space provided during playback with the E-800S.
