Listening to…

Music, that’s all about….

Opening gravity

Listening to “Opening” by Philip Glass was a flashback to times in my life long passed. Strange mix of love, sadness and fragility of some memories that linger in the air. Feels like floating, despite having not lifted a millimeter from ground. And who cares…

DHT sound

20120704-221126.jpg

Unique tone from a DHT valve. Haven’t experienced it?, worth trying…

Listening to Trane

Listening to Trane has been something I enjoyed so much since I started playing the saxophone. Joy to my ears…

Don’t you agree?

Listening to 01a

A warm and subtle tone, CX301a…
Superb sound!

Listening to headphone amplifier

20120526-093205.jpg
Just a dream. I will get to build that nice OTL headphone amp. Can’t complain though, I enjoy so much listening to my 45 SE with headphones….
