Want to purchase HQPlayer, but about it's more robust features?

So, this statement is why I asked the questions in the previous post. So, your saying your DAC is running at its default settings (given that some DACs can upsample?) while you use HQP to do any upsample you may want?

 

Hi vvcv!  All DACs that are not NOS upsample internally using the provided filters in the DAC chip (some FPGA based DACs have their own).  The idea with HQP is to replace the limited capabilities of on-board signal processing.  The chips don’t have the computing power to do the really complex filters that give the best sound.   Then it comes down to the talent of the filter designer / programmer- and in my humble opinion @Miska is far ahead of others.  He really understands the technical side and he tries to make each type of filter as technically accurate as possible.  As  @4est said there are trade offs to be made with each one.  

 

i have a DAC (Lampizator) that does nothing but use an analog filter circuit to convert the DSD stream to the analog output signal. I bought my DAC because of how good HQP is!

@vvcv   I should explain a little more... there are filters in a DAC chip, or in HQP, that shape the Digital signal going to the d to a conversion step and then to the output of the chip through into the signal sent out to a preamp or amp.   There are always hardware (reconstruction) filters in a DAC component.  The digital filters are what HQP does so if you upsample to the max rate your DAC can take they usually bypass their own filters.  My dCS will upsample everything to DSD128 before converting to analog, but if you send DSD128 it doesn’t use its internal upsampling filters.  Hope that helps!

@vvcv  Keep the "digital filter" and analog filter separate.  All DACs have an analog filter that the signal must pass through on it's way to the outputs.  HQP is intended to replace the DAC chip's ASRC (usally) or Digital Processing.  I wasn't able to tell exactly from the Benchmark "technology" tab on the webpage (mostly marketing speak) exactly whether or not it's internal DSP would be bypassed when sent a max rate signal.  It may still do some processing either way.  Many DACs bypass that when fed a max rate signal.
