Quick comparison with the Little Dot MK VII+.
At about $100 cheaper than the LD with shipping (complete cost of my build), the option of op amp rolling is what makes this amp so great. Not just the cost. With the two ICs, stock and the LM4562, this amp's sound quality is very close to the LD. When biasing the LM4562 into class A, the Balance Lovely Cube "BLC" I think is quite equal to the LD. There is some give and take. Little differences between the two but I am very happy with either one. With this quick comparison I won't be getting into the specifics of the sound but I can say that either one of these amps is easily worth more than what they cost.
Running the BLC with the Burson dual op amps will put it's cost close the the LD but the sound is better. It may not be apparent at first listen but then you begin to pick up things like better micro detail, sound stage, headroom, separation and placement. From what I'm hearing, the LD might end up on the for sale forum.
