In making a product, a company has to make choices on features. Bryston opted not to include selectable filters on its BDA-3. Its fine with me as the unit still punches well out of its price category. The BDA-3 has HDMI inputs where most D/A converters don't offer it. One cannot have everything in life. The BDA-3 has every feature that would interest me which is the reason I purchased it. The fact that a less expensive D/A converter offer filters is meaningless.
I agree the BDA-3 is a very good DAC within it's price range.
There is nothing wrong with asking for additional functionality. Many companies add new software features to their products during
it's lifespan, to make it's product more attractive to new buyers. I own a number of products where companies have done this even
after it's product was 2+ years old. This is very common these days.
If they feel there is a need for the filter selection, they may allow it in the BDA-3 or may even put it in the BDA-4.
There is a large group of people who like to tweak their music with filters, and this would open up a wider audience for sales.
Remember bryston did not like room correction and it was never available in the SP3. Now the SP4 is here, so is the option for
room correction. Why? More sales...
