Dac selections
It is complimented with 3 pairs of speakers in stereo.A total of 14 drivers all overlapping the audio spectrum...no sub required.I took the missions off as they were a bit heavy on the mid-range.Sound is life! 
Dac selections
I made my choice many years back and enjoy every beat from digital as well as analog, Rotel RDP980.Pity I cant show you a pic of the logic...a pcb full of top end caps and i/c's.Blows the mind...beautiful audio. 
Anyone heard the Meridian 559 amp
The output transistors are only available in TO220 on the net today...you wont need any unless you put a bus bar over the output.10 x 50amp per side..40 in total and i think they used the same as the predrivers for each channel.5amp continuous on ... 
Anyone heard the Meridian 559 amp
I reworked a Meridian Old school power amp for a customer. One or perhaps the most powerful retro PA I have ever seen. It had a monster toroidal, caps the size of 500ml beer cans and a few 100 amps worth of transistors per channel.Ran tests on a ... 
Why Power Cables Affect Sound
CAPS, the bigger the better, pump the current...limit voltage drops and drive the spl.Most transformers, the most expensive and important part have become so small over the years...but monster caps refreshed at 50-60 times per second does the job.... 
Big speakers in small room at moderate volume levels
have 5 Mission M Cube speakers, going to give those a try, 2 per channel on stereo...xmas present from a customer...best present in many years, one can never have enough speakers...more drivers the better..overlap says it all..  
Big speakers in small room at moderate volume levels
Small room I use JBL control 1 pro, amazing tone from such a small pair, 60wrms x 2 is more than enough.I have run various small boxes and some are way above the rest..budget forced jbl and i was more than happy.Still have a pair of retro swt1's, ... 
Are ferrites effective for cabling?
I stand under correction but we wind 10 turns of the cable in a loop for vhf transmission lines to remove any stray rf, perhaps this will work for audio... 
Budget hi-fi and vintage audio gear
A 3020 nad will do the job and thr retro sound will blow you away, if you find one have the complete pcb re soldered and pots/switches serviced with wd40.Tighten up the 3055's, output transistors and re solder them.I rework around 36 a year and th... 
This question is aimed to TRUE Elec Engineers, not fuse or wire directionality believers.
Hi GibbsI was referring to the main drivers that will burn, I am well aware of the audio bypass cap on tweeters...which wont pass dc.ANDthere are speakers out there with a resistor to limit the tops, so they could be smoked.Many retro speaker syst... 
How good's your hearing
Time to refresh your ears by listening to a nad 3020, where quality stereo began.It will change your perception of most new type avrs and digital systems.Love retro!  
Beware of SACD Transports -- they probably will not work with your favorite DAC
Copy the disc if not compatible.Done hundreds of dvd with dvd descriptor and dvd shrink.CD with total video convertor.If its a copy of your original its legal. 
This question is aimed to TRUE Elec Engineers, not fuse or wire directionality believers.
failure with no fuse could burn your speakers and the amp pcb ...you flip the coin if it really makes a difference in what your ears tell you. 
Threat of fire from audio equipment
the rotel 980 cda and dap are only switched on when used.heaven forbid one of them die on me, they are the best i have ever owned.cant take a chance with transformer items as our supply can hit 320vavc when a substation burns up, common in our new... 
Threat of fire from audio equipment
seen many cheap chinese power amp/mixers pcbs catch fire, mostly small components.I leave all my equipment switched on, especially avr's which have the fate of not coming on again.Cant afford to loose my hk5000, the 4000 went that way.
