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.

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.
Few more thoughts on PS Audio's sound. These are some very early thoughts, I need to do more listening to clear my thoughts on these.

Instruments sounds either panned fully to left, fully to right or in some blurry are in between. Things in between doesn't sound very focused. Don't get me wrong, instruments sound very distinct tonally, so very distinct. However, I don't yet feel positional distinction.

Will do more listening tomorrow and report! :D
@auxinput Yeah, emotiva was quite a disappointment for me :( Gave my system a Car HiFi feel.

I am guessing that Rotel is no slouch in terms of internal components. Some of it's beauty can be seen here. https://youtu.be/zCro9sPHda0?t=24s I can see the advantages of PS Audio's design though, minimalistic, sound focused design.

You are right, PS Audio walks all over Parasound. From my experience they are not even in the same league.
Alright,, pressing Ok button on Harmony for LG TV mutes the PS Audio :D If I would decide to go for PS Audio, I would definitely need to work out some IR control plan :D
Rotel's dealer seems to be closed today :( I won't be able to A/B compare PS Audio and Rotel.

Anyway, I am thinking that I will go for Rotel if I can make sure that it can be noise free somehow. Putting sound quality aside, that IR problem is a big deal breaker for me. I am not willing to change my tv for a preamp. Just bought the tv like 4 months ago. :/ I had one idea to get it working: tape over the IR receiver of LG tv, and use it's own remote instead of Harmony remote (LG remote works via bluetooth as I understand, or some 2.4g rf signal). This way, PS Audio's remote wouldn't be controlling TV, yet I would be able to control the TV. When I tried it, LG remote in some cases still sends IR commands, for example when TV is turned off. Besides, giving up on harmony remote also doesn't sound very nice to me. If PS Audio had RS232 control port, I could use that to make my own IR receiver and pass commands to PS Audio, but no RS232 port on it :/

In terms of SQ, from what I remember of Rotel, I would put PS Audio and Rotel at the same level, Rotel being easier to listen to, PS Audio being more revealing and more difficult to listen to for long durations.

I will be returning PS Audio on Tuesday, probably will go for Rotel purchase right after that. I still have 2 more days to change my mind though :D
