Are integrated amps technically better than separates?

 If money is no issue separates can often reach a higher level of performance (think Vinnie Rossi L2 + Pass monoblocs) provided ancillaries are top notch.  But some integrated (Ypsilon Phaeton, Bakoon amp13r) are absolutely splendid and costs -30/-50% of the equivalent separates solution delivering better value for money and a more elegant setup.  

I will give my 2 cents on this matter being involved in this mad science that we all call a "hobby" ! As previously stated everything comes with a price point ....the more your willing to spend the better your system will sound ! If your budget is unlimited separates will always win in the end because of flexibility ! Saying that; to me it comes to what you listen too and what speakers you are going to base your system on . Over the years I have used Musical Fidelity { back then called British Fidelity ) A1 ( 20 watts of glorious Class A power) , Forte separates ,both Class A & a monster 200 watt beast ,McCormack Micro series complete system even using their Micro amps as 2 mono's , Audible Illusion system and Assorted Conrad Johnson products including their CAV 50 integrated ! Each system mixing and matching sounded great depending on my speaker choice . After over 30 years of being able to purchase these used components has come to this : synergy within the same product line is real & not a advertisement gimmick ! To these old ears but together they always sound better ! After all on this BS from me I have settled for just 2 set-ups that I rotate about every 6 months. The CJ CAV 50 ( also very high (WAF) because of ease of use and the Audible Illusion's ! Speakers used , also rotated , Vandersteen 1 C's , Totem Arro's , Thiel '1.5 's and ERA 5 's . What i really like about the CAV 50 is the sound that only tubes can create and if the 45 watts of power is not enough you can bypass and use it as a preamp ! Only drawback is that there is no remote version available . Highly recommended !

I have owned separates (PS Audio BHK Amp and pre Amp). I now own a Luxman L509 integrated Amp.  Can I / could I tell the difference? Not a chance.  They both sound great.  Not convinced most people could differentiate between the two.  Another thing that needs to be mentioned is the volume I listen to music.  Unlike a visit to an audio store where we crank up the volume on equipment we are auditioning, I don't listen to recordings at anywhere near that level.  So that alone makes it tough to evaluate the performance of one's equipment - separates or integrated.  At the end of the day, I determined that the place to get the most bang for the listening buck are speakers.  

When you know what you want, and you want the best, a specialist is what you need.

he first statement is true. The second needs more explanation; as far as I can see its false. Regarding the first statement, over the years I've found that a lot of the improvements I've been able to make in our gear have related to power supplies. Arguably that's one of the trickier things that goes on in an integrated amp; IME it outweighs many of the other circuit topography issues! I totally get the connectivity issue- that is an advantage. But in most cases, its not *enough* of an advantage.

I have to agree.  In our components we have large power supplies.  Why, they sound better.  We repair all types of equipment and as already stated, much of the upgrades are in the power supply section.  I wish that could be accomplished differently but so far, we have not heard something that can replace a well designed and built power supply.  Out DAC has a 30 pound power supply.
