So far so good. I'll go through the components individually a bit later on.

Poor neglected PhonoStage
Hmmm ... six months without a post. I really should try harder.
However, I have started posting more regularly on my cycling blog; velostage.blogspot.com
Not much development with the hifi situation either, although I probably have enough stuff collected for a bijou cd/lp/digital playback setup.
Maybe I should start about getting it all together.

HiFi 07 : Sennheiser HD580 Headphones
When the Sennheiser HD580 headphones came out in the UK they had a couple of bad reviews.
Consequentially, a few months later I just popped into my local hifi store and was offered these at an absolute bargain price. I mean, a fraction of their original cost. How could I refuse?
Well, I found nothing wrong with them. In fact they went on to be regarded as one of the top high-end headphones and are still regarded as classics. So much for hifi reviews. In the end, trust your ears.
These are great 'phones. Extremely comfortable, incredible sound, fantastic dynamics ... and even my Rio Karma can drive them.
At the moment I'm using them direct from my Marantz CD5001. Not quite as dynamic as through the Sansui, but still pretty good for recreational listening.
Vastly superior to your average .mp3 player and ear buds.

Stuff 01 : Rio Karma Music Player
I suppose it's inevitable that when you think about .mp3 music players the first one that springs to mind is the Apple iPod. So deeply has this item entrenched in our culture that it has become a generic term in itself, just like in the UK all vacuum cleaners are Hoovers and all vacuum flasks are Thermoses.
It's a pity because there are some other good, and I dare say, even better .mp3 players out there. Linda got a Zune for Christmas and I think it's a pretty good job. I'd like one myself except for one important feature. A large percentage of my music collection has been digitised using either the .ogg codec or the .flac lossless compression codec and currently the Zune cannot play those codecs, although there are rumours of firmware updates in the future ... yeah! right!!!
.ogg is a superior form of lossy codec, similar to .mp3, but with advantages in the performance / listening area. .flac is the hifi of digital codecs and when used with clients such as ExactAudioCopy and addons such as AccurateRip provide computer music files which enable rendition as good as the original source material. More about this in a future blog ...
So it was as much as by luck as good judgment that several years ago I bought a Rio Karma .mp3 player. Luck, because at that time I was not aware of developments such as lossless codecs and gapless play. At first it seemed quite clunky compared to the iPods then available. But as a piece of ergonomic design it sits in your right hand and as well as playing music files enables you to compile play lists, adjust the 5-bad equalizer and lots of other refinements unique to the Karma all without interrupting the music.
Added to the equation is its excellent amplifier which can even drive my Sennheiser HD-580s to high volume and 15 hour battery life, this was a compact device with seriously hifi credentials. For sure it had weaknesses, especially in its software interface and Hitachi HDD. This saw the death of my first two Karmas. Touch wood my current example is lasting well.
Naturally, everybody bought iPods and the Karma remained a cult item until it was stopped being manufactured a few years ago. However, you only have to listen to one rendering a .flac encoded track through the very best headphones to realise this really is a little gem.
Now the few remaining working examples are much sought after and also the subject of fairly extreme modding in order to keep them going.
For a long time it looked as if we'd never see the likes of it again, but about a year ago a German company, TrekStor introduced the Vibez which utilised and built upon much of the electronics and firmware it had acquired from Rio.
By all accounts it is excellent and a big improvement in many areas, although I hear the amplifier is not in the same class as the Karma, necessitating using an additional headamp for critical use.

HiFi 04 : Sansui AU-317 MkII
I bought this Sansui AU-317 MkII integrated amplifier in 1978. If I recall it was about ukp400.00; about the price of a good example on eBay today.
The Sansui is very nicely built - virtually aircraft standard - and to me sounds great.
A useful feature is that the preamplifier and the amplifier can be separated. They are linked via a set of RCA connects on the back. It also has a phono-stage for connection to a record turntable and a sub-phono filter feature. This is necessary because the amp's frequency response runs down to dc and the filter stops your bass speakers transporting in and out with the warps on your lp records.
It can drive two sets of speakers either separately or together which I hope will enable me to have a play with bi-wiring at some point.
The problem I have here is that my particular amplifier was made for the European market. It has a voltage selector on the back, but this switches between 220v/240v @50Hz - rather a fine distinction.
Fortunately, I found this device, the Quick 220, which in practice supplies about 235v@60Hz. The amp seems to run well on this and so far, I haven't found the 60Hz supply to be a problem. I anticipated some extra heat, but this doesn't seem apparent.
There are some snags with the amp, mostly of a consequence of the time it was built. The RCA plugs are not gold-plated, appearing to be made of nickel-silver which has dulled over the years. But they're clean and otherwise uncorroded and I can't detect any performance issues as a result.
More seriously, the speaker terminals are of the quick-fit variety rather than nice stud-type terminals. However, if you take care over the insertion of the speaker cables, it doesn't appear to be a problem.
Lastly, I managed to find the amplifier's product manual in .pdf format and now available here. It also includes details of the AU-117 and AU-217 amps.

HiFi 02 : Sum Of The Parts
I have always had an interest in hifi. That is; the facility to reproduce music with as practical an approach to fidelity as reasonable and economic.
I say reasonable. I have heard some incredible rigs at hifi shows and at dealers. Some have cost into six figures - and I'm talking UKpounds here.
But probably the best system I ever heard cost in the region of UKp4k at a show in Bristol some years ago. Still a lot of money, but I'll bet lots of people round here spend a lot more than that on their home theatre/cinema system.
As I recall, the rig was in the Wilson-Benesch room, consisting of one of their turntables and speakers playing through a Chord amplifier. The demo disc was Lou Reed, Walk on the Wild Side. And in the bit the coloured girls go, Doo doo ... you could place every singer in the chorus at an exact place in the room. Nice. I hasten to add, the image to the left represents home theatre overkill, not a modest hifi setup.
Anyway, what I am doing is putting together a system from favourite and found bits and pieces with the occasional purchase, coping with the 110v/220v problem and producing a modest, but practical and competent system.
Next HiFi article; 110v/220v and why it's an issue for me.
