An interview with Kevin Hayes Of VAC. The KT88 and the 300b tube are some of the most popular options for HiFi amplification. But what are the differences and why do some amp designers choose one over the other? Kevin explains the situation and also discusses Class A, if amplifiers "warm up", and if tubes sound better in the pre amp or power amp. A very educational and inspirational interview with a tube designer that has been in the business for over 35 years.

A huge show with an interview of Nicholas Niespodziani from Yacht Rock Revue! The term "Yacht Rock" is turning out to be quite the hot button topic for audiophiles. With the release of the HBO doc Yacht Rock: A DOCKUMENTARY and Donald Fagan's white hot response to the idea, it has quickly become apparent that not everyone is in love with the term that has caused a massive resurgence in interest from LA-based soft rock bands from the mid 70s and 80s.

Yacht Rock Revue has been at the head of that resurgence, riding the wave with musicianship and showmanship like no other. With a massive groundswell of their own, Nick and the YRR crew have not only collaborated with the artists they cover, but have even opened up for Kenny Loggins on tour. Now a music force in their own right, YRR has released two original albums "Hot Dads In Tight Jeans" and the recent "Escape Artist". 

In this episode we discuss whether the term "Yacht Rock" is offensive, a mild slight, or downright condescending. Nick offers a unique perspective from someone on the front lines, and shares stories from his experience leading arguably one of the most successful cover bands of all time.
