There're heated competition between Chi-Fi companies recently. making an A50 is not a good business decision anymore as D50 is unbalanced. SMSL offers a more attractive solution (SU-8 and SH-8) at the same price. They should just cancel that product line entirely.
What they could do is
- upgrade DX7s to have better amps --- A lot of people and reviews love the product except the buffer stage uses TPA6120, which results to high internal impedance.
- make the top flagship product based on 9038 Pro with good amp, so it can compete directly with SMSL VMV D1. dual 9038 Pro DAC is not necessary as Oppo already demonstrated with their last bluray player. So that can cut the cost significantly down, and one would expect it to be within $600.
- make a new product based on 4997 with good amp, that can compete directly with SMSL M10. (SMSL uses TPA6120A2 so not good for low impedance headphones)
After all, amplifiers are much, much cheaper than DAC (chip cost, design cost, manufacture cost). Selling a DAC with great amp doesn't add too much additional cost, but can attract a lot of users.
