Description

My latest updates to my single-ended 2-channel audio system (as of 2006).

These latest additions consist of a pair of 1998 Triangle Electroacoustique Zephyr 2-way towers, which, even at 90dB levels are amazingly dynamic and extremely detailed with my flea-powered 6.5 watt SET amp (although they're an easy load at 4 ohms, I wish they were more sensitive than their 91dB rating).

Adding a pair of 100 watt active subwoofers definitely add that tight, low end punch most suitable for the blues, jazz, classic rock, large orchestral compositions, and for all my digital pipe organ recordings!

And I'm glad to be spinning vinyl once again with my dad's vintage '79 Technics SL-1700MK2 turntable and my equally trusty '84 Stanton 981HZS pro calibrated MM cartridge. Even though this is not your high-end audiophile, mega-dollar belt-driven setup with a $1500 tonearm, $3000 tube phono stage, and a $5000 low-output MC cartridge, this mint Technics is still rock-steady and deadly accurate in my opinion, with my discontinued Stanton MM cartridge still making my remastered 180 gram LPs sound even better than some CDs! Remember, this 'table was originally designed for the audio consumer, long before today's DJs discovered their ruggedness and reliability. And someday soon I hope to replace my entry-level Music Hall phono stage with a vacuum tube phono pre, but for now the mmf-phono pack will do.

It's a never-ending process, this audio hobby of ours, and I'm sure there'll be more upgrades to come...stay tuned.

Great to see you're still enjoying a Nak cassette deck! You're probably like me as have lots of great music on tape (along with CD's and vinyl).

Thanks for sharing!
