Cable for my amp.


Hi,

how do i find out whether my amp takes 15A or 20A power cables??

I have a Mark Levinson 27
thx
yingying99
my setup is:
ML 26 Pre
ML 27
Denon DCD 3500G CDP
Sonus Faber Cremona Auditor
VanDenHul Magnum spk cables.
Power Condit, some cheapo brand from Asia.....

wanted to upgrade CDP to Audia Flight CD ONE or ML 390S and Hydra 4 maybe.

yes, an odd setup I know, SF with ML. most ppl use Macs or tubes wiht auditors... but wiht this setup, the transparacy is amazing. wide soundstage. and that "live" feeling of female vocals is what made me fall in love with this setup.

so far quite impressed with the sound. I auditioned the same spks with Krell 400xi + Stnd SACD, which was a faster sounding system then mine, but musically, mine kicks A$$!

and yes, my 27 sounded more controlled with the bass when plugs directly into mains, but not overwhelmingly so. I made every effort to eliminate any "boominess" with the bass, trying spikes, feets for spk stands, cables etc.
my speaker cables are good value for money and sounded better than a pair of Gold Ref Cardas I tried recently.

tell me what u think.

also, this 390S CDP is on sale at the moment, is he reliable as he has no +ve feedback and asking for money order only.... mmm...
YY -- do not lump all power devices into the same category. There are basically 4 kinds of devices:

1. Regenerators
2. Conditioners
3. Isolation transformers
4. Balanced power units

The first device to try is really not a device: dedicated circuit(s) with or without isolation (transformers)

1.) REGENERATORS: If you can't install DCs for some reason, the next best thing is a power regenerator. Basically a PR takes wall current -- dirty, noisy, fluctuating, inaccurate wall power -- and "re-manufactures" it into perfect, theoretically ideal AC power. The best (most electrically efficient) one currently on the market IMO is the ExactPower EP-15A.

2.) CONDITIONERS: Power conditioner/surge protector units, including a very well respected one named after one of the Greek Furies, are basically an assemblage of chokes and other filters plus some fast acting diodes. They can filter and cancel most line noise, but they do not improve the quality of the wall AC itself, and they do not offer meaningful protection against voltage spikes. The internal components they use can greatly slow down energy transfer (especially important for amps) rendering even the biggest power cords useless. I totally pass on these devices, and so should everyone (in my ever-so-humble opinion!)

3.) ISO TRANSFORMERS: These can be used with regular wall AC, dedicated circuits, regnerators or balanced power units. They are most often found with dedicated circuits and no other devices. They offer excellent protection from ground spikes (lightening) line noise and some powerline irregularities. They need to be large capacity to work with big amps, and can be expensive, but seem to be most popular with audiophiles who are also electrical engineers -- they must know something ;--)

4.) Balanced power units are an excellent way to provide quiet -- really quiet! -- power to source components. They represent a "finishing touch" after you have done dedicated circuits and/or 1 or 3. They usually do not improve amplifier performance, so buying one with sufficient capacity to handle an amplifier is not cost-efficient.

Your electronics and speakers are a nice combo, regardless of what other ppl use. If you ever have the chance to score/upgrade to a 26s and/or a 27.5 or 23.5 do it, and keep the speakers.

The 390S is in the top ten. It's not in the top three, but would have good synergy with your 26 -- use the balanced interconnects with it -- either Madrigal CZ GEL or PAD Venustas. Also use balanced PAD Venustas ICs between the 26 and 27 and for the spkr cables.

Get rid of the cheap power conditioner but don't spend money on an expensive one! If dedicated circuits can be installed DO IT before spending money on ANY power devices. If they can't be installed, then get an EP-15A and plug everything into it. That may be all you ever need.

thx Nsgarch for your input!

i cannot install a dedicated line in my home. hence have to deal with what i have got.

so u would recommend investing in an EP15A rather than say a Hydra 2??

is the EP15A switchable to 220V?? thx
Sam and YY, the Shunyata Hydra is one of the most popular power conditioners. Please re-read my comments on these devices. Even though it's very expensive, the Hydra is still just a conditioner, and therefore in my opinion, not the best use of your money. And when used with amps, can actually degrade performance. I guess their power cords are OK, I've never tried one.

YY, you would be best served with an EP-15A. I don't think they are switchable but I'm sure you could get a 220V version. Check with Brent Jackson at the factory:

I forgot to mention that the Exactpower units (both the regnerator and the balanced power unit) also have a couple of outlets with filters to trap digital noise your DAC or CDP power cords can send back into the power lines. This is a really good thing, and why people who install dedicated circuits often put in an extra one just for their digital gear.
