today i got my new Focal Electra 1038BE ,help

Sounds good, Kzhtoo. However, I would go with the Audio Research over the NAD.

Kzhtoo

sound great!
i didn't thought about Mac mini , small and powerful
how can i upgrade the power supply?

didn't understand:
if the DAC have PRE built in , why i need to buy also PRE?

i spoke with 1038 owner , he tried many options
he like PRE with Tube and power Amp
but finally he bought Simaudio 700i (maybe to save space on the living room , not sure why)
what do you think ?

because i'm new to the HI-FI world , maybe i need to start small and later to sell and upgrade?
what will be the best AMP for lower value?
if i will get 90% from the lower value amp instead of 100% from XA60.5 it will be ok with me

for DAC
what are my options?
Audio Research or NAD M51 , are the best or should i consider more models?

what about this integrated amp?

Hi Pelo,
Mac mini can wait. I was just laying out what I think is an incredible set of gears to bring out the true potential of 1038 Be. If you already have a PC with optical out, I'd rather buy a reclocker first to clean up the jitter first (as mentioned in a previous thread, $600 Empirical Audio Synchro-mesh reclocker will make it very worthwhile).

Most DAC don't have a built-in pre, what they have is volume control, mostly digital. Benchmark dac1 pre may be what you are seeking, DAC + an analog volume control (I prefer analog volume control than digital one).

You could try out Simaudio integrated but not my cup of tea. This is what fascinating about this hobby. Not being my taste should have no bearing on what you'd like. Try it if the price is within your comfortable range, you might like it and think "what the hack kzhtoo is talking about".

This is exactly what I've been saying. You are new..no need to go overboard on the amp. Pass XA30.5 is more than enough for your efficient 93db 1038 Be. Used price is around $3.5k here on A'gon. And there's always Parasound, you can get A21, a well reviewed performer, for under $2k, excellent starting point!

$1.2k Metrum Octave will give you 90% of NAD M51. Your money your decision. If you're looking for under $1k, there are plenty to choose from. If you want a volume control with your DAC, go with Benchmark.

Also, may be a good idea to re-read this entire thread. What you thought a couple of weeks ago might not be what you think right now. I'm sure you have been researching and gained some knowledge.

Once again, Kzhtoo, you have presented sound advice.
