Detailed store usage guide
Swipe right to learn how to choose from the many models that are right for you.
Select a product (TAP1-PRO as an example)

There are four different opamp options, and the sound is all different. When purchasing upgrade options, remember to purchase ontology options!
The option "muses02" is the opamp of your current option. If you purchase this option, your TAP1-PRO will be configured with muses02.
If you chose the V7 vivid*4, then we will configure your TAP1-PRO with the Burson V7 Vivid*4, which includes the opamp adapter and acrylic cover.
There are also two upgrade options, once you purchase these two upgrade options, we will help you to replace the muses02 with ss3602 or 627bp. If the upgrade option is purchased separately, the amplifier and PSU-2 are not included. It is only marketed as an opamp upgrade option.

Some TAP1-PRO peripherals. Choose according to your preference.

The combination of design and comfort
Look no further for the perfect headphone amplifier! KAEI DESIGN is definitely for you, guaranteed to feast your ears!

We will also release our portable decoder cables and earphones in the future. The following earphones are not KAEI DESIGN brands, they are collaborative products in which we participated in adjusting the sound quality, and they are also available for purchase now.
TAP1
It is a better tube headphone amplifier than the TAP2, and comes standard with the muses02 amplifier chip. Electronic material is better than TAP2. The sound is better, too. You can choose to upgrade the DAC version (cs43198DAC chip), which can be directly connected to your PC and phone via USB, without using a DAC, DAP or dongle. You can choose to purchase a psu-2 power supply with built-in voltage. Bypassing the TAP1 internal battery when in use, the power and listening experience will be better.

TAP1-PRO
It is an enhanced version of the TAP1, with some electronic components optimized. The sound is different from the TAP1. The main output and resolution power and other comparisons TAP1 parameters have hardly changed. The Tap1-Pro has been upgraded for the case, which is 3mm thinner than the TAP1. The glass cover has a magnet, and the opamp can be easily replaced using the included suction cup. One of the features of TAP1-PRO is the option of sparkos ss3602 version, we will modify the ss3602 pin to fit TAP1-PRO. Let the TAP1-PRO accommodate a larger opamp. At the same time, we offer the most advanced Burson V7 Vivid version, if you choose this version, we will add an opamp adapter and acrylic cover. The Burson V7 version of the TAP1-PRO will be primarily a desktop model, not a portable headphone amplifier.

DAP6-PRO
Excellent and interesting decoding tool for iPhone7/8/se2/se3. Can turn your idle iphone into an ios DAP!
You can switch to PC mode and use it like "DAC" without an iPhone. (Connect PC and phone via USB)
The built-in iPhone can normally use the SIM card, Internet calls. Play music games.
If you have a spare iPhone7/8/se2/se3, DAP6 is your best bet. (Cost performance will be very high)
You can also choose to buy the built-in iphone version (which will cost more).
