Studio Monitors?, Low budget!! Options

[Hamish]

I am on a very low budget approx £300 and I need monitors. What can anyone recommend? Active, or an Amp and monitors. Please help!

I can try! I have BM5 nearfields driven with a Smartlight amp chucking out 300 W RMS per side. Smartlight are a British company and I stumbled on them quite by accident, very impressed but had never heard of them before. I've also heard BM's running on about 5 other systems with the standard 50-100W per side arrangement (you know, alesis type things that get bundled with BM5's quite often, hifi amps and better like Hafler, Yamaha).
Observations? Well I felt the overpowered setup produces a very, very much tighter controlled sound, particularly focused bottom end well suited to the Dynaudio driver across their range of monitors (M1's also work amazingly this way). More broadly speaking and to the point, I love the dynamic range. Words like effortless and unstrained spring to mind . Most people visiting my studio stroke their chin in an approving way and look slightly quizzically at the amp! I guess that's good?

My crtl room pot on the desk rarely makes it past 11o'clock, levels on the amp wound to max -why introduce any more stages of attenuation than neccessary to the signal path.

Bm6 'A' s are unfamiliar to me I'm afraid. I just have a gut feeling that it would be more expensive to put more power than 'neccessary' into a unit such as this and therefore an unlikely costing to be factored into the design process. I've no doubt these sound lovely given what dynaudio are capable of and have certainly been carefully tailored to the BM6, I just like the big amp thing .

In general, I believe it is less healthy to push a low powered amp run close to it's output limit for long periods of time through a monitor, than running a more than double spec'd amp at half it's output capability. Closer to the headroom of the amp's maximum output, it's more likely for continuous clipping to occur at this stage in the signal chain -especially with seriously compressed audio. Bye Bye tweeters!

As for valve amps, don't know how to eloquently explain the techy aspect with any concision The power ratings are always spec'd lower -but drive much harder, and sound better in terms of dynamics at lower powers. I know a few hifi buffs who have confirmed my thoughts regarding transistor amps sounding best when overpowered and underdriven. Check the links for some blurb that may go some way to explaining this.

Class A push-pull output stages are inherently distortion-cancelling and each amplifying device, be it valve or transistor, operates in a complementary electrical sense at all times. Deviations of performance from the ideal of either device are compensated by the other. But with so-called Class B stages, one transistor of a pair is constantly switching in and out of operation, handing over to the other transistor during its period of no operation. An obvious difficulty here is to achieve a smooth changeover or 'crossover' (not to be confused with loudspeaker dividing networks), and the main reason for the 'transistor sound' of most early (and unfortunately some present-day) transistorised amplifiers is/was poor crossover performance (where the switch from one transistor to another failed to give perfect signal continuity) leading to a spiky distortion most evident at low Output levels and high frequencies. Many transistor amplifiers actually had better performance at high output levels, quite the reverse of most good quality valved amps.

Monitoring is a pretty subjective experience at the end of the day. Valves may be sweeter with a detailed top end (though expensive for one worth having), transistor amps perhaps more neutral/less 'warm'? Certainly much, much cheaper and easier to maintain for similar 'build quality' of product.
The tonality is a matter of taste. Slightly overdriven (-not sure about this for monitoring accurately?)/valvey-smooth, or neutral (as far as is theoretically possible for any speaker) depending on what you like and how other well known programme is produced and compares..

..but the reproduction of dynamics is critical for me at least and is fortunately a fairly well understood problem for transistors and valves alike.

Hope this helps (someone! ) xxx
