For thrills, kicks and to satisfy any urge to tinker, I am now seeking out the perfect pencil, which is just as time-consuming, but less expensive.

I've tried some of the more expensive brands such as Derwent but I find that the basic Staedtler 110 Tradition cedar wood pencil with either a B or 2B grade graphite is the best for general use.

 

Don't waste your time on the ones that have erasers on the end because the pink rubber leaves a mark on the paper. mad You should use a separate eraser anyway, they're much better. Staedtler make very good erasers too IMO.

 

Hope this information helps with your exciting journey of pencil discovery atticus. excellent!

Well I am a self-confessed bass freak.

Is the single 10" woofer in a relatively small sealed box that's used in the AVI subwoofer really the last word in bass reproduction? Or is it possible to find better bass from other speakers or subwoofers?

May I be so bold to put forward the Ken Kreisel DXD808 sub. Probably the most detailed sub around, and "invisible" for both movies and music. Pretty amazing depth as well for the size of it. Given that it uses exactly the same dual push-pull amplifiers used in its bigger brother, you'd be hard pushed to better it.

Although if you're a real bass freak, a bigger ported box may be more your thing. But I'm comparing like for like Smile

Since others in another thread are being asked to ammend signatures wouldn't it be pertinent to update your signature to mention that you're the UK exclusive dealer for Ken Kreisel if you're going to recommend his products?

http://www.hifix.co.uk/hifi/audio/miller-kreisel-reborn/

After all it's no different to being a manufacturer really since if someone in the UK buys that sub it will have to be through your company. Just in the interests of perceived impartiality.

RE: Kef ls50 or avi adm9rs or other?

@ the OP:  As you can tell by how this thread has gone, only you can determine whether the KEFs or AVIs are right for you. Most people have not heard both and even if they did it would just be their subjective opinions. Clearly both the LS50 & ADM9RS are fine products in their own rights, so you just need to find the one that is right for you.

 

 

Re: the overall AVI debate - Even ignoring whether you like the head honcho at the company or not, there are still some issues that cause problems for potential customers:

 

1) The claim is that the typical passive route is essentially audiophoolery and that buying a pair of AVI actives will break the cycle of upgraditis. That's straight up nonsense - there are many members of the AVI forums who have upgraded from one model of the ADM9 to the next and/or to the ADM40s. So the cycle has not been broken. So rippng on other HiFi companies about their upgrade paths is just hypocricy (especially when AVI customers are not discouraged from buying the whole AVI catalog).

 

2) The idea that in general actives are more accurate/just better than passives. While actives generally offer great (often better value for money), you only need to visit a pro audio forum or read user reviews on a site that sells pro monitors and you'll quickly see that not all actives are great. Pro users complain about monitors sounding distorted, overly bright, rolled off, bass shy, bass heavy, etc etc etc. Better yet go to a pro store and audition some monitors yourself, then you can say whether actives are just better than passives.

It was in answer to this:

As for ammending signature, I don't believe WHF would want a long list of manufacturer's in our signatures (personally, I don't mind). Although if I mention the brand in my sig specifically, it will be promoting it on a constant basis - again, I don't think that will be something that WHF would want. We negotiated for exclusivity because we know how good his products are, and have every faith in its performance. But like other products, I'm not going to recommend it just because I have it - I will recommend it where I see it is relevant.

Actually they are. ("Whole catalogue"? Three products!)

In general, anything can be badly designed/made. The essential principle is entirely correct.

When you say that "The essential principle is entirely correct", do you mean that you think that an active crossover as used in the AVI ADM9rs will result in less THD+N than a passive crossover as used in the KEF LS50 at ALL volume levels and frequencies?

No. I mean an active configuration is always better than passive (for any particular speaker).
