We don't do instant bans, Classic, and we try to keep our egos firmly in check. Point taken, though, we've all had a giggle and the ad hominem should stop now.

I do think Tony is a bit Paranoid if he thinks your posts will affect his sales. Just to remind people that personal attacks amount to ad hominem. Tony reading your so called humorous comments suggests you may be turning into another Marco. Instant ban elsewhere. And DQ please stop quoting my signature.  Classic I'll have you know my psychiatry account has been steadily declining over the years so it all good  Now comparing myself to Marco way beyond the pale sir!!! shame on you boo hiss  |

naim audios 6x135`s amps(six pack) and naim dbl`s after a couple of minutes you will be playing air guitar and the drums at the same time Or "FBL's" as I Remember a review of them saying. Effin' big loudspeakers... No no substitute for cubic inches... |

I have never heard DBLs sound good. In fact, they have reminded me of rather uncouth disco speakers in the past. Shocking for the price.

Never heard 'em. The Naim boys like them?

The Harbeth discussion on Hoffman forum drew my attention to this. www.harbeth.co.uk/usergroup/showthread.php?2613-How-much-amplifier-power-do-I-REALLY-need&p=34629#post34629A discussion of how much power you need to give full dynamic range. The video put up by Alan Shaw suggests it all depends on music type but for loud electronic music hundreds of watts was found to be desirable. There appears to be an emphasis on real power rather than subtle audiophile amp design. People are still swearing they can drive Harbeth 40.1 with 9W single ended valve amps when in most situations this must be patently untrue. |

Alan also attempted to demonstrate this at Bristol this year, I am sure people who visited the room can comment on this, a great many where leaving the room with smiles on their faces

I seem to remember bringing up this very subject a while ago to comments such as "my 40W per channel is plenty" and such. Using the calculations, my 550W per channel is barely adequate for my needs.

I really do think depends on the drvers and arrangement Martin
So mid and treble I do not need that power but with my bass I do
Different systems different approaches

Isn't eliminating "lossy factors" in a speaker part of the answer? The concrete speakers commercially available one time were supposed to have some wallop to their bass. I would imagine this was down to their rigid enclosures that didn't honk away and smear the output. Don't know what drivers they used or how complex the crossover was.

A few years I was fortunate enough to own a pair of top if the line eagles tone works cabinets solid granite bass cited at 13hz -4/5db
My only critique was simple you could 'hear' drivers as the cabinets were so dead, oh they did weigh over 900lbs
These boys did 7 on the slam o meter though they did require a solid 70 amps of current to do this
Dynamic swing is an important part of musical reproduction though tonal quality layering, micro, macro details tight articulate textured bass is also required as well

So the power requirements are not atypical and I agree that it's mostly in the bass (but more needed in the midrange than many people expect). I want my dynamics uncurtailed and clean and it needs a lot of clean undistorted watts to achieve that. I got the power wrong, my Chord actually outputs 620Wpc into 4 ohms (my speakers). |

I'm glad I went down the Naim route years ago,my house was like a a demo room with all the loaned bits from lintone audio every couple of weeks,went through krell,acoustic research,mus fid and others,happy with the Naim sound does what I want it to do plays music and stops me from all the tweaking and wasting load of money on bits and then changing them,still use the mana stands though

There's more to it than power specs: I've come down in power from the Chord's 620Wpc to the Belles' 200Wpc (my speakers are 4 ohm) and yet I have more slam than ever. Peak current gives the real game away: it's 32A for the Belles.

hi martin,i used a a pair of mus fid A370 power amps and a mvt pre amp fedding a pair of acoustic enegy 1`s for a while with a rel studio sub that was interesting,never had to heat the room ,they ran hot it was like having a 3 bar electric fire on ,they loved the juice,but the image and sound stage front to back was amazing,it was that far out of the speakers the sing was sitting on my knee,ut the electric meter was spinning.big reduction on electric bill,when is sold them on,they ran hot,pretty good sound tho.

I remember the big Musical Fidelitys, they certainly did run hot.
Op-amp driven quintuple MOSFET push-pull output stage, according to that circuit.

Reading some of the early threads, amazing how people heard 'Slam' from old design speakers  |

I've certainly heard slam from older model JBLs, Altecs and Cerwin-Vegas.
