4 amplifiers to drive 1 pair of speakers?

Hi @atmasphere 

Thanks for sharing the idea on monostrapping! Was reading up on it. How about what if I do not monostrap? Monostrap kind of puts the amplifiers in series if Im not wrong? So if I place the amplifiers at parrallel will they actually sound more musical/less harsh and heavy handed?

Thanks

Hi 

I am using kef reference 5 with recommended 50-400W needed to power it. Most of the impedence on the chart is around 4ohm instead of 8 ohms. Lowest dips to 3.2 ohms. Although it is 90db at 8 ohms, there are 4 woofers, 1 tweeter and 1 midrange on each speaker - hence may require more power/current. 

From what I understand tube amps (or at least SET amps - not 100% applicable here as they are PP) should not be pushed past their 25% limit to have a good sound.Hence for a 18W 300b PP monoblock amplfier to drive my speakers will likely be insufficient. Hence exploration of 4 amplifiers and whether anyone has tried it before/if it is feasible. 

@scchengmus what do you mean by power ratio calculation? Why will there be equipment failure? :) sorry am not well versed in that

Thanks

Hi Erik and Oldhvymec,

Thanks for your suggestion for the bi-amping with solid state for bass. However I note from some reviews eg Steve Guttenberg it isnt that easy to get a good matching of the amplifiers (eg he tried with zen triode at the top and schiit aegir at the bottom end) and it wasnt a good match.

Hence I was apprehensive about bi-amping. I know some solutions eg Mcintosh MC901 sounds really good, but those are out of my budget and also it is a pre-matched solution.

Thanks!

@atmasphere thanks for your advice! :)) ok sure will go and look for the dynaco manual! :))

Always thankful for pros like you giving advice! :)) 🙏🙏

@hshifi thanks! Im actually using primaluma...just tt i prefer the sound of big tubes eg 300b, 211 , 845. Im thinking of different solutions I can use to circumvent the power problem

@boomerbillone wow thanks for sharing! Haha 8 channels must sound really powerful! Hahaha if I have a chance would be great to listen to your system! Haha I have seen videos on Thomas & Stereo where he shows off someones system using 3 mcintosh amplifiers 1 high 1 mid 1 low. Looks really magnificent hahaha
Will your set up work without a electronic crossover?

@douglas_schroeder  thanks for your input! :) haha wow you sound very experienced! Oic! Always was wondering why I dont see multiple amplifiers rather than 1 stereo / pair of monoblocks used! I guess that must be the reason! 

Ok sure, looking forward to your article! Haha so what amplifiers are you using currently? Your speakers are the legacy audio speakers?

@douglas_schroeder  haha ok sure will check out your reviews! Haha interesting surprise gear you are going to review

Haha I probably lean way more towards the tube camp :p when I have enough funds will want to upgrade to horns with low powered tubes actually :pp what do you feel is lost? 

Thanks
