What is Floyd Toole saying about extra amplifier power and headroom?
Remedies for unacceptable situations typically included spending more money on a loudspeaker with a “better” woofer (without useful technical specifications, that was a lottery of another kind) and a bigger amplifier (for useless headroom ...
@erik_squires When it comes to Convoluton filters what I have now was created by a rock star in the field, not by some random DIY’er who thinks they are an expert after tinkering around. This was done by a professional audio engineer doing this for 20+ years and has written a book on this issue. What I have now is the best tweak or upgrade to my system. I do not know if you hang out in the Computer Audiophile site but my filters were created based on info posted there. Some very knowledge folks on this issue over there. I am posting my findings here because most folks on this site are not aware of the possibilities with Convolution. My Convolution files was created using Audiolense which I understand is some very complicated software (Accurate is another option). It is also not free, like REW. I had to pay $200 for a 1 time license usage of the software by the outsourced audio expert. The implementation cost was another $500. Peanuts from my perspective. I paid more for an XLR interconnect and that had 0.00145% the benefit of the Convolution. What I solved was getting a big speaker into a small room and getting it sounding perfect. That was my goal from the start and mission accomplished. It took me 2 years to get to this destination from the start of this thread. https://forum.audiogon.com/discussions/big-speakers-in-small-room-at-moderate-volume-levels?highligh... With regards to ROON setup, I have a 2 computer solution. My client computer was picked out of the trash 5 years ago from an previous employer. My ROON Core server is a under $1K DELL refurbished machine. It has something like 20 cores and 32 Gigs of RAM. This is actually my weakest server in the house, I have about 10 computers in the house. ROON Core does not need that much power, even with Convolution. If you go to the ROON forums and ask the ROON developers there they will tell you the same. I had a buddy over to my office today. I had him sit at my desk and I played the music. He had the same reaction I am having, glorious sound. I have actually heard enough uber systems and other non-uber great systems to know that my system is now also great. |
Speaking of amps that will truly, "Double Down". The only one's, "theoretically" that will, that I know of are the Pass "Aleph 0's". I had a pair of the, "Aleph 2" but I never really ran them hard. Very nice amps though..... "Erik"? You mentioned a "Mythical" Krell, 50 watt amp also? Do you by any chance mean the KHA-100 mono-blocks? I have a pair sitting here. And cannot seem to find anything much about them. Large though. |
MC is very wrong again on many accounts. Headroom - this is where an amp can really shine in producing high instant peaks and crescendos. If any amp, listening amp, guitar/bass amp, pushing an amp too hard will cause distortion, clipping, or possibly shut it down. Headroom is a buffer of sorts, just like the car you drive, do you always need 300hp to go to the store? No, but when passing or trailering you might hedge that way. MC always gives his wisdom on speaker sensitivity and since he thinks his low fi speakers are 94db rated, he tells everybody to ignore speakers less than 90+db efficient. He ignores a few reviews of tekton speakers where the reviewer actually measured tekton 7db lower than the rated 94db from the manufacturer. If this is the case, which I’m guessing is fact since 1 of the trade mags does measurement tests and MC doesn’t, I would think MC would follow his own advice and start looking for a quality speaker this time around that’s 90+db efficient. IMO, it’s foolish to state a speaker needs to be greater than 90db unless you want to use a low powered SET amp, then by all means look for a high efficient speaker. |
