Little Dot MK 2 II Headphone Amp Amplifier/Pre-Amp!

The Little Dot MK II Headphone Tube Amplifier/Pre-Amp

A newly designed SEPP (single-ended push pull) OTL circuit operating in Class-A, the Little Dot MK II greatly increases sound quality, dynamic range, output impedance, and harmonic distortion over the celebrated Little Dot II++. 
The Little Dot MK II now also provides gain control of 3, 5, and 10 via internal DIP switches for fine-tuning so you can maximize synergy with almost any headphone you have, whether it be 32 ohms or 600!
The Little Dot MK II also gains the driver tube-rolling options from the rest of the MK-series with the ability to roll 6JI, WE403A/B, GE5654, M8100, CV4010, EF95, etc at its factory jumper setting, and with jumper pins shorted, EF92, CV131, and all equivalents and drop-in replacements!

Power Cord Note: Little Dot amplifiers ships with a standard Type-B power cord (American 3-pin or U-ground) suitable for use in areas such as North America, Japan, Taiwan, etc.  If your country's outlets use other power cord types (ex. Schuko) you will need a power cord of your own plug type.  You likely have several spares around your home, as any standard power cord (like your computer's power cord) will work perfectly fine.  We do apologize for any inconvenience!

Warranty and Support:

Are you intrigued by our Little Dot amplifiers but worry about the process if, Heaven forbid, something were to go wrong?  Rest assured, our Little Dot products are backed by arguably the best, and most customer-friendly warranty policy in the business for your peace of mind!  Please do note however that our warranty and support only applies to Little Dot amplifiers sold through direct sales (i.e. this eBay listing) or our Authorized resellers.  We cannot provide any warranty or support for Little Dots acquired through unauthorized or gray market sellers (i.e. other sellers).

•  If on the chance a functional problem arises within the first 3 months (we've found that if issues occur, the vast majority crop up within the first month or two) of your warranty period and you send it back to us for repair, we will reimburse you the full return shipping amount once we receive it so there is absolutely no out-of-pocket cost to you!

•     From 3 months until the end of your warranty period, if a functional problem arises we will reimburse you for half of the return shipping cost once we receive it.

•     From warranty expiration to as long as you own your Little Dot, repair/labor/parts are always free - the only thing you are responsible for is shipping costs.

•     Vacuum tubes are not covered under warranty as they are a consumable item, however if there are functional issues with a tube, we can provide a free replacement(s) for just the cost of shipping.

As you can see, we stand behind our products and are fully committed to providing the best ownership experience we can provide.  Again, our warranty only applies to Little Dots sold through direct or authorized resellers as otherwise we cannot guarantee the initial quality and A-stock, new status of Little Dots sold through unauthorized or gray market sellers.
