Sunday Photos Show: The Bottlehead Crack Amplifier

I made this photo shoot on Sunday morning when I listening the music through my headphones along with the Bottlehead Crack and newly upgrade hybrid vacuum tube op-amps headphone amplifier here and here.

I actually find that this hybrid vacuum tube op-amps amplifier sound so good that can match with the big brother, is the Bottlehead Crack. With the total built cost for this hybrid vacuum tube op-amps amplifier is only one quarter cost of the Bottlehead Crack, I think it can be considerably a budget audiophile headphone amplifier.

The sound characteristic between them is very similar. Kind of neutral with extended high frequency and lot of micro details. The Bottlehead Crack gives more three dimensional and more aura in midrange. It is also warmer in sound presentation. It drives most headphones with ease and this creating more dynamic to the sound.

The hybrid vacuum tube op-amps amplifier is more compact and simple to carry around. It powered with 12 volt DC power supply or using 3 piece of 18650 lithium batteries. This amplifier drives any headphones relatively ease but lesser power output than the Bottlehead Crack.

So here are the Sunday photos show, they are consist of:

The reason is simply because of the op-amps variation are hundreds and they are depends by the implementation.

Vintage Multibit R2R DAC Tier List

At the very beginning of this year, I committed to explore the best multi-bit R2R DAC.

Then I will rank them up in a simple tier list. The reason for this, so you all know what my opinion about of those vintage multibit R2R DAC especially in the sound quality.

What Mazda Bose Centerpoint Does to The Music?

It has been a month since I bought and use this brand-new Mazda CX-5 as my daily cars. No doubt for the car performance, this is one of the most reliable, yet very comfortable car to drive. This Mazda CX-5 is the Elite version with 2.5-liter engine and package with Bose audio system as a "bonus" features. This is car is very interesting, I will try to explain it from my own perspectives as a casual user, especially for the Bose audio system. Early disclaimer, I listening to this Bose audio system and in my opinion, the overall sound quality is not very special. Surprise, surprise! The sound quality is average but for sure better than most cars with non-audio brand collaboration. Let's deep down to it.
