ATMOSPHERE ADDED

In the beginning! THIS SECTION WAS REVISED Feb 2008 My interest in hifi dates back to the late 70's. My best mate at School, Stephen owned a really cool pair of American Jensen dual cone full range speakers. These things had real bass and worked well with "NEW WAVE". I was bitten by the bug soon after and I have never recovered. It is a brilliant hobby with so many avenues to follow. Initially I was just listening, then reading/buying, then designing and building your own equipment (highly recommend if you have appropriate skills), system matching, tuning the room, the history, retro gear, buying, selling. When you read these pages you may learn a little of my passion. My first system featured a BSR BDS95 turntable with ADC VLM, a ROTEL RA214 amp and a pair of Wharfedale Denton XP2s. Black vinyl was my only source for a very long time (1978-1988) This was followed by a huge range of gear. The best of the early items included the Rotel RA1000, A+R A60 amp, Mordaunt Short Festivals, Mission 763, Croft Super Micro, EPOS ES14 and the Quad FM4 MY LONGEST STANDING PIECE OF EQUIPMENT?? I USED A AR LEGEND DAILY between OCTOBER 1983 and June 2005 (22 years of faithful service) I first heard CD running on Hitachi's first CD player. The HA-1000 (not sure about the designation) It was extremely impressive back in 1982. The Bose 901s generating a gale of very clear sounds. I was completely shocked when I heard the first Marantz CD player (top loader CD63) playing through some Quad ELS 63s. At the time I couldn't believe it could possibly get any better. My first CD player was a third generation Yamaha CDX-810 HiBit (18bit with 8 times over sampling) My current systems are a strange mix of old and new but all three work very well indeed and all have different strengths and weaknesses. From June 2005 I have decided to move to all digital source components. I honestly believe that a turntable is the best sonic solution. However, they just require too much work and getting good quality music out of other sources has become relatively easy.

MY BEST SMALL SPEAKER SO FAR
This speaker started out life as a Sanyo SX 50 a nice 2 way system built in NZ. Jane picked up the boxes at a local OP SHOP for $2. I had them in pieces in about 5 mins. The original bass drivers were good but both tweeters had blown. The boxes were in a fairly tatty condition and had been water damaged. A light grey plastic veneer was showing some lift. The boxes were just about to be dropped in the bin when I realized that the veneer could be peeled off quite easily. The MDF underneath was actually not bad so I decided to sand them back The space once occupied by the cone tweeter now houses a 70mm plastic port. The box has been painted with grey primer and two coats of CHOC. The box is upside down. Internally they have been lined with Yamaha felt and wool. I have kept this away from the back of the port. A gasket was placed around the larger bass hole and I have fitted a Coral 4A-70 driver. I have used very ordinary internal cable because I find that the thin stuff solders properly. (much more satisfactory than some thick OFC which brings no benefit in such a short run) These are really wonderful small speakers. They fit my metal stands perfectly and the drivers are at ear height when I am sitting and listening The 4A-70 produce wonderful tight bass in this size enclosure . The mid treble and imaging arte absolutely spot on I use them with my Sony VFET and a Passion Passive

I also own some stunning Yamaha NS 1000M studio monitors. |

my guidelines 1. Use good quality interconnects and speaker cable. At least O.F.C. or better. Clean all plugs and sockets with contact cleaner. If you have time try to buy lengths of silver wire (say 0.5mm) from the people who supply the jewellers and make your own. 2. I often use passive preamps simply because they add nothing to the sound. In my experience the best passive controllers are built by Audio Synthesis in the UK. Rothwell electronics also make a similar device. You could also consider building one. A cheap blue 50K ohm ALPS pot in a box will give good resultsThere are some great new designs around. Check out MF audio based in the UK. Their passive uses transformers with multiple taps In my view the ideal system, is still based upon a turntable, moving coil cartridge, passive pre/solid state power amp (class A) , or a neutral solid state preamp and Valve power amp ( I prefer the Mullard 5-10 variants EL84)A high efficiency single full range drive unit. or hybrid electrostatic (FR electrostatics have to be large) Experiment with old Alnico drive units. These may look uncool and lack fancy heavy magnets and heavy lifeless cones. But they sound much much better. The Alnico magnets are far far superior. I have just built a tiny 9L ported enclosure which house two 70's alnico SEAS drivers. It is so good its hard to describe. It has great pace, bass tempo and rhythm. IE MUSIC. Most speakers I hear miss the target 3.Amplifiers. Use a valve power amp or a class A solid state.. Buy or build in the biggest power supply you can. Buy or build an amplifier which has the minimum of discrete components. With each component come an extra character and yet another solder joint. Bad news for the audio signal!!!!! 4. I have been listening to speakers for a long time. If you have a big unconditionally stable amplifier and lots of money it really is difficult to beat electrostatic loudspeakers. Quad, Vass audio etc. If you have to use a normal dynamic loudspeaker, find one with a single, well made, full range drive unit. ,Kef UniQ, Bandor, Crysler or if you get lucky a Coral beta 8 or 10. The reason being they are usually easy to drive and they will give you an image. Also look out for 50, 60s drivers featuring Alnico drivers OTHER POINTS Use a simple vocal recording to check for the centre image. You will easily spot phase problems with speakers. Tweeters should be at ear height in your seated position. Lift speakers off the floor and keep them away from room corners if possible. (both help tune the bass)
