The amplifier will have approx 30watt per channel power. It can drive most low to medium impedance bookshelf speaker nicely. It is superb for using on your desktop, in a small to medium size listening environment, together with the D1 DAC, you will be surprised how powerful this small mini amplifier is.
We don’t use cheap Class-D chip in this amplifier. It is an “old school” Class A/B integrated amplifier when we use two tubes as preamp stage. It is fast, yet has the distinct smooth/warm tube flavor.
The headphone output is pure tube driven. You will have two choice — a pair of matched Chinese made 6J1 NOS tube or the western equivalent — a pair of matched Military grade 6AK5/5654 tube. We have acquired a large quantity of 1950 era Tung-Sol 6AK5/5654 tube directly from an US military base. Based on my testing, the headphone amp output on this amplifier along, is as good or better than a lot dedicated headphone amp on the market.
What would be the approximate prices?
It will be priced similar to the D1. We want to keep our product affordable
Hi, So when will it be out??
We are looking for early July release time. We will probably start to take pre-order end of this month.
Is the headphone jack going to be more power than the D1? Any Impedance tolerance restrictions? What will the frequency response range be?
Yes the headphone output will be much more powerful than the D1.
Frequency response range will be 20Hz–25KHz.
Input impedance 100KOhmOutput Impedance 4Ohm to 8Ohm
