Minute 300B amp can connect up to 5 music sources at the back with build-in volume control. There is a special input in the front panel which has an option to bypass the build-in volume control.

The output transformers can be wired to 4 ohm, 8 ohm, or 16 ohm.

Shipping weight : 30kg.

The 12″ big horn ribbons produce a dynamic, transparent and immediate sound that other drivers cannot do.

Crossover is made of Obbligato film caps. Film caps are very expensive but you can hear big differences.

Subwoofer is active and adjustable according to your preferences.

The overall result is a 20hz to 30khz flat frequency response – truly high fidelity.

Price: ₱310,000 for a pair. This is the last pair!

MINI TUBE AMP (in stock in Manila)

Mini Tube Amp is so small that it can fit in bedroom, office desk etc. With 90dB speakers we can listen comfortably in a 30sq meter room. The amplifier is small but sound amazingly good.

Output transformer is made of premium Z-11 core.

Output is 3.5w + 3.5w, 4/6/8 ohms.

Price : ₱16,500 including tubes.

Warranty: 24-months on amp. 12-months on tubes.

Warning: The tube runs very hot. Please put it away from children. Please use it with good ventilation to avoid overheating which will void the warranty.

CHAZZ II TUBE HEAD PHONE AMP (in stock in Manila)

OTL through film caps. MUCH much better clarity, finesse and speed as compared to electrolytics.

It uses two 12aU7 instead of one 12Ax7 for it’s less distortion. The difference is noticeable to those with a taste for the high end.

The volume control is a carbon attenuate for warmer sound. We don’t like plastic in between us and the music. The downside of carbon pot is that there may be some frying pan noise when adjusting the volume.

Regular Price : ₱24,000

Special Price: ₱15,000
