@daledeee1 I was curious to test Lampizator tube DACs, but have not gotten around to it yet because the local dealer was quite out of the way. The simple reason that we keep hearing Denafrips and Musician being recommended is simply because they had been aggressive in providing review units to reviewers and media. And it helps also the DACs really punch above their price point.
I mean, yes, there are better DACs than Musician Aquarius and Denafrips Terminator Plus (disclaimer: have not heard Terminator Plus yet), but most of them are prohibitively expensive like Mola Mola Tambaqui and MSB Discrete, though some of them have quietly dropped their price realizing the competition. Aqua La Scala MKII is actually cheaper than Terminator Plus in my city. These other brands are definitely more niche and depend more on word of mouth for marketing, but if you are fortunate enough to have local dealers definitely should give them a listen. I recently replaced my Pegasus with Lab12 Reference Dac1 and I could not be happier.
