Experiment #1 in full swing. Big thanks to
teuchter for lending me his spare speakers and amp for a vintage audiophile perspective.
The speakers are the classic Kef 105 / 2s.
They're a lovely design, pretty big for hifi speakers, carry 12" woofers and are rated up to 200 watts.
I didn't bother attaching my old NAD 3020 as it would be a bit small. My valve amp and 1000W PA amp are both slightly damaged at the moment so neither was able to drive them very well. I then set them up with the amp teuchter used for them, the classic 1980's Audiolab 8000A.
From the first they were really impressive. Having listened to a 2000 watt PA rig for 20 years it was great to hear detailed sound which wasn't just pure brute air shifting power. Had a real treat running through some favourite tunes, and then testing it out on some classic jungle etc, enjoying a depth of sound I haven't been used to in decades.
The amp is rated at 60 watts per channel but in the usual audiophile gumph it's described as a big 60W with the necessary high current required to run these speakers. Good though it sounded I was keen to hear what another 25 years of advances in modern amplifier technology might sound like. I eventually plumped for the Cambridge Audio Azur 651, at the bigger end of hifi power ratings with 75 watts per channel, and including extra features like USB and jack inputs to play from laptops, phones, tablets, etc
When I first wired it up I wasn't sure at all, it didn't seem to be very loud or clear and I was struggling to see any improvement on the old Audiolab. The instructions demanded that it be run in for 160 hours continuously before it would sound at its best. I decided that was almost certainly bollocks.
I set up one amp on one speaker and the other on the second speaker for a proper comparison test, both set on direct to ignore the treble/bass controls. The Audiolab had to be on half volume to get the Kefs sounding good. The CA had to be on 3/4 volume to match the same volume. This would appear to be at odds with the wattage rating supplied by the manufacturers, and just the sort of thing which gets audiophiles wanking on about 'proper' watts and high current.
Now that they were set up to play at the same I could hear the difference, and confirm that these speakers just demand a lot of juice before they sound really good. To my surprise the new CA sounded nicer, fuller and all round better. Within 10 minutes I had decided that I would never go back to a full sound system and then the next two nights playing records of different styles and genres as if hearing them for the first time. All doubts that a hifi system could play reggae properly without my beloved 18" woofers were firmly put to bed as the house resonated with deep, rich bass, and vocals have never sounded so sweet.
A great start to the experiment, hope it doesn't get too addictive. Next up I'm trying to get hold of some TDL RTL 3's, and possibly some Celestion Ditton 44's.
