Delve deep into the world of audiophile amplifiers as host Lachlan chats with Andrew, Alisa and Lutz from Sparkos Labs - renowned manufacturers of discrete op-amps and the Aries and Gemini headphone amplifiers. Unravel the enigmatic nuances of tube amplification, starting with the intriguing insights into the Gemini's tuning for the 6922 tubes and Andrew's personal favorite tubes for the amp.
Discover the impact of bias settings on the amplifier's sound signature. Understand the intricacies of circuit design, distinguishing between discrete and integrated designs and their effects on sound quality.
The conversation delves into the role of feedback in amplifiers—when it enhances performance and when it leads to undesirable outcomes. Explore the reasons behind some amps sounding "lifeless" and the merits of single-ended amplification for harmonic content.
Andrew sheds light on technical concepts like truth about balanced vs single-ended and their partnership with Geshelli Labs, offering a peek into future developments in Sparkos products.
