well, it has been 1 week since i have recieved my "upgraded" isabella,named isabella lfp-v edition.
the upgrade involved adding a much improved type of battery. this battery is a lithium phosphorus type,with many added benefits
over sla type batterys.
for those interested in learning more about this new battery technology,i suggest checking out red wine audio web site for more detailed information. the other modification done was having the headphone jack installed on the front panel(via a new face plate)
ok,let me start by saying,that i am a firm believer of "off the grid audio" i have owned in the past,many pre-amps and headphone/pre-amps,some being quite pricey, that all used ac wall power! some were linear types and some were switched type power supplies.i have also used power conditioners,power regenerators and fancy power cords,all with the intention of getting as clean of an a/c input as possible.
no dice!
a/c powered audio devices just do not cut it anymore for me, after getting a taste of what red wine audio has to offer.
there is nothing like clean high current battery power attached to fully discrete(no opamps) boards and discrete tube output stages!
all with the shortest signal paths. i cant think of a better design.
in my opinion,the lfp-v edition of the isabella is a huge upgrade!
vinnie of "rwa" claims these new batterys deliver more actual current to your drivers. we all know,and any audiophile will tell you that "clean current" is a key ingredient to great sound.
well, i can attest that the lfp-v power delivers in spades! here are the differences the way i hear them between sla isabella and
lfp-v isabella.
SLA TYPE offers -(dead quiet background)-( natural tone and timber)- (realistic & believable sound)- (excellent details)-(wide soundstage)
LFP-V TYPE offers-(more dead quiet background,scary quiet)-(more natural tone and timber)-(more liquid sounding,that you can almost taste)
(more realistic & believable sound,almost as if my entire body from head to toe is immersed in the music)- (details galore! try the audeze lcd-2
headphones with alo lux-fep cables! you wont believe your ears!)-(wider soundstage)
the isabella sla and lfp-v have the same house sound,and i strongly suggest tube rolling! the isabella is worthy of the best tubes you can afford! and the differences in tubes is not subtle imo.
