I cut and pasted an excerpt from the description on the Manley Laboratories website, written on their phono stage model, Chinook. I own one and can speak highly of its sonic performance. In fact, it's the best sounding phono stage component I have ever owned (having several over the years past). My turntable is 8 feet from my main line-stage preamp. I have the Chinook located just below the turntable, with the phono connection being the standard 1.2M length. I use an Audioquest cable run of 3M from the Chinook to my line-stage preamp. There is absolutely no trouble running that length. Zero noise, no loss of signal strength, fabulous sound. I am running a modest output MC cartridge of 0.6mv, which is a Lyra Delos. Anyway, this setup works very well and sounds wonderful. Read the paragraph below and then log on to the Manley Laboratories website for further information. I hope this helps you. Good luck on your quest.
Like the Steelhead, each channel employs the two triode sections of a 6922 for amplifying duties with highly accurate passive RIAA equalization networks. In the Chinook, the signal is then directly coupled to another 6922 dual triode serving as the output driver in a White Follower configuration. This output stage circuit is our favorite because of its super-low output impedance and beefy current-driving capabilities. It can drive long cable lengths and difficult loads, tube or solid-state. Bring it on. No wimpy cathode followers here!
