Preamp: Parasound P5 vs Rotel RC1590

Hi everyone!

I have a choice to make between Parasound P5 and Rotel RC1590. Will be using them with Hypex NCore NC500 based monoblock amps and Focal Electra 1008be speakers. Will be using XLR output, and ht bypass is a must.

Out of these 2 choices, which one would you recommend ? Listed some of the pros and cons I am thinking of each model.

Parasound P5:
  • Many positive reviews
  • Subwoofer integration
  • True ht bypass
  • Looks visually better than Rotel.
cons:
  • No torodial transformer, switching power supply instead.
  • Motorized volume control. (possible lack of precise control at low volumes, harder to control via remote probably)

Rotel RC1590:
  • 2 toroidal transforms (1 is dedicated to DAC)
  • Built in DAC is of a higher spec.
  • Digital volume control
  • RS232 connection. I use home automation system (HASS). I could build a device to control the amp in anyway I want.
cons:
  • Fixed gain instead of ht bypass, would need to have balance set to 0 or compensate for it by AVR.
  • No proper subwoofer integration. However I can easily DIY a cross over filter and volume pot, to connect to sub. My sub has independent LFE and L/R inputs.

Now, I know that these items are priced very differently in states. But, in Poland, their retail prices are more or less identical. Rotel seems to be much better of a preamp for the money (speaking only of the components inside: http://www.rotel.com/sites/default/files/rc1590_guts.png). However, there are fewer reviews of it, very few user reviews. Features and spec wise,  RC-1570 or RC-1572 seems to be more comparable to Parasound P5 and they are much cheaper than Parasound here.

Some guidance would be very much appreciated.

Glad to help, Denizpiri.  I'm puzzled at the background hiss you are hearing from either unit.  There is no way you should be experiencing this, but it has me wondering what the power grid is like in Poland where you are.  I also have not experienced any imbalance at low volumes, and that should be a deal breaker for you.

Is it possible that one or more of your line level cables are running along side of one of your power cables?  This could induce noise into the sound, but you may know this already!

As far as the DAC goes, the president of Parasound has said it's more of a convenience than an audiophile grade unit, so the Rotel should better it.

Returned the P5 this morning, and got Emotiva XSP-1 from another dealer. Started trying Emotiva about 4 hours ago. Only advantage I can see with it is that it has almost no noise regardless of how close I get to tweeters. However, sounds really really poor. Bass is really slow, mid range sounds scooped, vocals are not focused. I was scheduled to return Emotiva on Tuesday, but I am taking it back tomorrow.

So far, Rotel RC-1590 > Parasound P5 >> Emotiva XSP-1.

Today, while returning the P5, I saw a PS Audio Stellar Gain DAC / Pre, asked a bit about it, later on checked it online. I will try to take it for home demo tomorrow and see how it sounds. Price wise it is somewhat better priced than P5, it is $1700 in US, around $2200 here in Poland, probably can get it for $2000.
Will read more about it now and see if it's feature set perfectly suits my needs.

I have had very similar results with several other Emotiva preamp/DACs.  They are just not good devices.

I think the PS Audio Stellar Gain will be the best out of all your choices.  It has a very large toroidal transformer and uses linear power supply for both DAC and preamp (no switching power supplies at all!!).  The Class A audio stage will be very high resolution and I think it will be a better match to your Class D amps, which tend to be very clean and somewhat sterile/flat.  I think the PS Audio will give you a lot more life and excitement in the music - much more engaging than the Parasound P5 or any Rotel option.

I'm afraid my experience with Emotiva was also not stellar. It was reliable, sturdy, and quiet. Sounded thin as hell. There was nothing really enjoyable about the sound quality. As some one who is always out bargain hunting, that was a big disappointment for me. 

I ended up selling it along with the upgrade card and switching to a Parasound P7 and Oppo BD player.

PS Audio is home now, listening to it as I am writing this. It is scheduled to be returned on Monday.

Honestly, I am kind of sad. I was hoping to bring it home and that somehow it wouldn't match with my system, sound poor and make my decision very clear. However, that is not the case. Sounds so very good! If I would need to describe the sound in 2 words: REVEALING & BASS.
Pros:
- It is very revealing. I can hear details I never heard before.
- Insanely strong bass. It doesn't die down as the volume goes down. Almost as if a gentle Loudness effect is applied.
- Compact size
Cons:
- !!! My LG TV responds to it's IR commands!!! Pressing Optical Input button acts as the Netflix button on TV and turns it on and activates netflix app. PowerOn IR command for PS Audio turns TV on and activates Amazon app. Few other buttons also controls some other TV commands this way. Not sure what to do about this one. :/
- In some songs, bass completely dominates. It is not that it takes over the upper range or midrange, it still stands on it's own very distinctly. However, It forces me to turn the volume down since things around the flat start shaking.
- Very revealing nature can be a curse in some tracks. Makes it not easy to listen to when every few secs you hear something wrong with the recording process of the song. Not sure if this is much of a negative. I will listen more in upcoming days and see.
- Almost the same amount of noise as Rotel has. So, I assume I have something wrong with my AC power.
- Somewhat cheaper looking comparing to the other units I tried. Especially the way OLED screen is mounted and that button on it's side doesn't look nice up close.
- Volume knob feel is quite poor.
- 8 screws on top panel, adds to the poor looks.

IR command problem of it and TV is really bad. However, I am currently controlling it with Harmony remote. Since device is for home demo, they didn't give it's original remote. Not sure if original remote's IR commands overlaps with LG TV's IR commands.

Another thing that is somewhat bothering me is that, after I purchased the Class D hypex ncore NC500 power amps, they were first started with Rotel RC-1590. And I had to return Rotel before the amps were properly burnt in. Since trying Rotel, amps had quite a bit of work out, and Class D amps are known to change their treble performance after first 20 hours or so of use. So, it is possible that Rotel would sound more clear right now.

I will see if store that sells Rotel is open tomorrow, if it is, I will try to take it for home demo as well and spend the Sunday doing A/B comparisons at home. My decision will definitely be between Rotel or PS Audio though. Both are great sounding products and has a "WOW" factor to their sound.
