Hello, I am new to Hifi Audio and currently have a Darkvoice tube amp and a SMSL Sanskrit 6th edition dac. I also have a Aune X8 Magic dac. I understand that different dac's can produce a different sound signature. But what about DAC's that have the same chipset such as the SMSL Sanskrit 6th versus the Topping D30 which use the same DAC chip? Can it be assumed that the sound signature will be the same or similar? I am going broke trying different brands of DAC's with different chipsets... I am feeding all of this through a Chromecast Audio dongle 3.5mm to toslink cable into the Sanskrit 6th then outputting to the Darkvoice tube amp. I love the sound but at what point do you stop buying stuff hoping to get that last ounce of perfection?
