  Stereopal Home Visit:   Tony from Toronto  Date:  Nov 15, 2008




When I walked into Tony's room, the first thing I noticed was the giant bass horns which are built into the wall.    Now he probably didn't go as far as this guy, but he is the only person I knew in Toronto who has this. The Bass horns are powered by four 15" woofers on each sides.  Unfortunately, they weren't hooked up while I was visiting.


Tony is a knowledgeable audiophile with plenty of hands on experience on circuitry, speaker building, and anything analog related.


His latest invention is a lifter mechanism for the RS-A1 tonearm.   I've always thought that the RS-A1 is a great tonearm but was hesitant to buy one because it doesnt have have a lifter.  Looks like Tony solved my problem.

  Room Treatment
Custom basement listening room with 2 built-in 30Hz bass horns. 2 x 6 stud construction with all walls and ceiling floating. Walls are laminated concrete boards with drywall. Side walls are non-parallel to eliminate flutter echo. Audio is powered by dedicated AC lines. Light dimming is performed by remotely controlled 1500VA variac not to create RFI due to light dimmers. Room has built-in conduits for possible surround cabling and digital cabling. Walls and ceiling are heavily insulated. Audio equipment is in a room adjacent to the listening room. Through the wall infrared remote control re-transmission is installed.







 Tony's Comments:



My audio journey started in Grade 9 on my way to high school admission exams when I picked up a ham/DIY audio magazine. I was hooked ever since and as a result I started building audio gear and went into electrical engineering. The first amplifier I built was a germanium 2 x 6W integrated. That was followed by speakers, tuner, more powerful quadraphonic amplifier, ... After coming to Canada I did not have time to build gear in early 1980's and bought commercial gear: H&K receiver, DUAL turntables, Nakamichi cassette deck and others. I was not too happy with the sound so in late 1980's building of audio equipment started again: JFET and OP AMP preamplifiers, solid state amplifiers, modifications of tuners, amplifiers, ... Then around 1990 I "discovered" triode tubes and high efficiency speakers and was hooked again. This was in pre-Internet days when it was very difficult to find any information about the emerging SET (single ended triode) movement. Sound Practices magazine was the main source of information in those days. I started building SET amplifiers, preamplifiers, highly efficient speakers and modifying tube equipment. I am slowly getting where I want to be with my equipment. One big project remains: a big 4 way horn speaker system. One day - maybe when I am retired?


More work is required on the phono set up to get it where I would like it to be. In the future, I want to set up my Garrard 301 on a new plinth. I am curious about its sound. I also want to get into the Tape Project to properly use my reel-to-reels. A very

long term plan is to implement the speaker system I wanted for the last 15 years: a 4 way all horn speaker system.

I mostly listen to jazz and classical music.
