Preamp recommendation


Are there any modern multichannel (5-7ch) preamps on the market currently? Something along the lines of parasound P7 and Mcintosh C45 (both discontinued)  Need this for home theater and 2 channel playback. Any recommendations?

Yes. I recommend not subjecting your two channel stereo to multi-channel dreck. If you want lots of channels buy a HT receiver. Put the money you save where it will actually get sound quality results: stereo.

I am on an Anthem STR revisit so I am coming across these links.
That would be called a surround processor. Check out Arcam they have a nice one.
If you like the Bryston sound, the SP3 processor is likely going to be an excellent candidate.  It has fully discrete Class A audio stages for BOTH the 7.1 RCA analog input stage as well as the fully balanced XLR analog output stages.  It is likely going to be the best 7.1 channel analog preamp you will find on today's market.
Bryston is around  4k used now. Anything under 1-2k used? Also need a 5 channel amp that would work with focal dome speakers without making them bright. Hoping to get both for around 2k total, used is ok.

Would a Parasound 5 channel amp sound good with focals?  
Are you looking for a 5 channel analog preamp?  (this means that you have a 5 channel source that is producing analog signals, such as the analog output from an Oppo 105/205).

Or are you looking for a preamp/processor, that is taking digital input such as audio from HDMI or digital COAX and decoding and converting it to analog output?
Ah, anyways, you're budget is very constrained.  Here's what you could probably realistically do:

Outlaw Audio 976 processor: $929
Monoprice Monolith 5x200 amp:  $1299

It's above you're budget, but it's worth stretching it.  It would be very hard to find something below this.  You can get a cheaper processor, but then you're looking at the very old stuff that is 12-17 years old (Krell HTS, Proceed AVP2, etc.).  These older devices are typically starting to fail around now.

Parasound amp would be okay.  The Parsound sound is slightly warm with soft rolled off highs.  That Parasound HCA-2205A amp on audiogon is an example.  I suspect the Monoprice Monolith might be a little cleaner and higher resolution.
I have an OPPO 205 analog out going to preamp. I don't need anything with a DAC. Just simple analog pre and an amp. 
Aux :

There is a Parasound P7 on eBay for around 1k. Possibly B stock, but says it's under warranty. I'm thinking about getting that and maybe another Krell KAV-500 which I currently own for my other setup. Price for both around 2k. Would that be better than outlaw and monolith? 

on a completely separate note:  Is there a way to connect an OPPO 205 main HDMI out to two different TV's at the same time without sacrificing quality? 
Yes, the Parasound P7 is definitely better than the Outlaw 976.  I googled for it.  Rather than trying to buy a b-stock from ebay, why not just buy a new one from Audio Advisor for the same price ($999).  They are currently having a 56% off sale on the P7 and you can have your choice of either silver or black.  I suspect that the P7 may be discontinued very soon.  Vendors typical do this type of sale right before the product is dropped.

Your Oppo 205 does have two HDMI outputs.  Even though the second output is labeled as "Audio Out", it will still output a full audio/video signal.  The difference between the outputs is the processing:

HDMI OUT (Audio Out):  This hdmi output will send raw unprocessed audio/video as it is read directly from the disc.  No processing or enhancement is applied to this output.

HDMI OUT (Main):  This hdmi output will also send audio/video, but it includes any processing or color adjustments that you make in the oppo menu for video adjustment, such as picture adjustment, DVD 24p conversion, de-interlacing, color, hue, noise reduction, etc.

So, you could use both hdmi outputs if you wanted.  But if you just want to use the MAIN output for two displays, you will need an HDMI Splitter.  The best 2-output splitter that I know of is the Gefen GTB-HD4K2K-142C-BLK.  You can get it for about $179 from BH Photo or Adarama.  If you upgrade the power supply adapter to a Teradak/Zerozone 5V linear power supply, it will improve the video quality as well.

You could get a cheap Monoprice Blackbird splitter for $85:

Monoprice has had an iffy history with it's hdmi products.  Some work out, but some are not reliable or don't work.  It's cheap, though.
As far as the amps, it's difficult.

The Monoprice Monolith is currently going to be the most transparent, cleanest and highest resolution of the three.  It has excellent and very full midrange tones.  However, it could be a little hard edged in the highs (especially with your Focal metal domes).

The Parasound HCA is going to be very smooth and very refined.  Very natural sounding, but not as transparent.  Rolled off highs and it's not going to be as exciting as the Monoprice.

The Krell KAV-500 might be better than both of these.  Much more refined, transparent and "truer" sounding than monoprice.  More resolution and exciting than Parasound.  It is a 20 year old amp, though, if this concerns you.  I see one on audiogon for $1400.  If you can get one in good condition for $1k, it might be really excellent.  I have no idea when these will start failing due to dried out capacitors and other parts that may fail over time.

Home Theater Integration, $0. Okay, all you "home theater bypass" guys. All of our preamps offer true home theater bypass. Just plug in your processor's front channels to any input, select Passive mode, and turn the volume all the way up. Presto! 1:1 home theater bypass, with only a relay in the signal path.

Thanks everyone for your input. 

Looking at Parasound A51 and A52+
I am correct to assume these would sound similar ? 
What are pros and cons of each? Is the price difference justified?  
Wow, did your budget go up? lol.

The sound between the A51 and A52+ is going to be very similar (if not the same).  The main difference is power / power supply.  Your Focal Dome speakers are not going to be too terribly hard to drive, so the difference between 180 watts per channel and 250 watts per channel is not going to make any significant amount of difference (in my opinion). 

The higher power of the A51 would be beneficial if you really large woofers and low impedance speakers.  The A51 might be just a little bit more smooth and full, but it is a significant amount more.
I find that budget always goes up no matter where you start, at least this is true for me. I think I'm leaning to Parasound P7 pre, and Krell KAV500 vs. A52+. 

Before making a final decision, I'm also looking at Anthem MRX520. Do you think the sound from Parasound/Krell would be better than Anthem via Focal dome speakers? Anthem reportedly has good room correction (ARC). Not sure how much of an effect that will have on sound. 

BY THE WAY: My older Krell KAV500 failed on me a year after I got it, needed to be recapped and again, one year later making strange popping noise through speakers while its on. I love the sound of Krell via Vienna acoustics speakers. 
The Anthem MRX receivers are very good and have very high resolution speed and attack.  The downside is that in some systems, the Anthem could sound too bright/harsh on the high frequencies.  This could definitely be the case with your Focal. If you went this direction (and possibly with the Monlith amp), I would recommend some nice copper solid-core speaker cable, such as Audioquest Rocket 33 or Type 8 or Type 4.  Also, use gold-plated terminations instead of silver.

The Parasound would definitely be more forgiving on the high frequencies.  You will likely have to spend a lot more to get a high resolution amp that is not bright, and you also should still avoid stranded speaker wire with anything silver or silver-plated.
If you are wandering around in the budget area of a Parasound A51, there is a Chord SPM-2400 five channel amp on audiogon for $2999 from a dealer.  This would be the next step up which would give you excellent resolution without being bright/harsh like the Anthem or Monolith.  It would not be warm with soft/rolled off highs like the Parasound.
Found a classe ca-5100 amplifier, brand new, NOS. for $2.5k. 
Anyone know this amp? Would it be a good match with Parasound P7 and focal speakers ? 
Wyred4Sound STP-SE - I have the standard model and I'm very satisfied. I can't imagine how the upgrade could be better.
You can find some great prices on Arcam right now on multichannel amps right now the line is changing 
I’m using a Lexicon MC-8B.

It has phenomenal musicality and it’s preamp section is wonderfully flexible. Mine has XLR abilities. I’m matching it with a multichannel Bryston amp with older B&W matrix speakers. 
It has the ability to take in multi-channel data on its optical inputs so it can still nicely get around HDMI needs for audio, and I just use the video sources direct to the TV.

The Lexicons were very well reviewed and have some incredible modes for multi channel as well as bypass if you want.  Other than possibly needing a new PS, which isn’t much or hard fo do, they are awesome. Pyramid in Texas does great service.

Hello!

Sorry to reboot an old thread but after reading many review for 5.1/7.1 preamps back in 2020, I ended up getting a Parasound P7 to drive 5.1 from an OPPO 205 to a McIntosh MC257.

1.5 years later... I removed the P7 without regret to replace it with a McIntosh C45 and my setup has been sounding good again.

My experience with the P7:

CONS:
1/ Humming from all speakers if not using XLR
2/ A/O amps noticeably clicking in and out when changing volume
3/ Voices/vocals/mids were somehow sent further from the sound stage, sounding weak and making me considering speakers maintenance.
4/ When powered off for a few days, the volume/control knob stops working completely for several days -- Parasound had to send me a replacement.
5/ Display can be turned off but the moment you use any control, it will come back up and not-redim
6/ Input description cannot use several common chars (such as dash -)
7/ P7 can’t bi-amp front using extra the unused channels in 5.1.
8/ Unused inputs cannot be turned off
9/ The POWER control to the MC257 would turned it on/off as expected but the lights on the amp would remain OFF, regardless of the control know. I tried to make custom cables to address this but it didn’t know.

It was globally sounding a little bright/harsh compared to patching directly from OPPO to Amp but brought convenience to inputs switching and reducing bass to avoid getting kicked out of my apartment by angry neighbors.

PROS:
1/ Better bass management -- but I do not/cannot have a subwoofer
2/ Tape out will down mix 5.1/7.1 to stereo (useful for spectrum analyzers, or VU Meters) -- but I can live without a muti-ch down-mix
3/ Input renaming
4/ MC/MM phono switch
5/ Bass/Treble can be adjusted from the remote
6/ I got one of the last discounted new units + racking kit before they were discontinued.

But the upgrade bug was always kicking and I finally found a McIntosh C45 for a good price and pulled the trigger.

With the coloration of the sound with the P7 well imprinted in my head after 1.5 years, the C45 differences were quite obvious. Most notably, the mids/vocals were back in front of the sound stage, not diluted in the back, and the sound was warm again, like McIntosh is famous for. Phono also sounded better with better bass and hissing mostly gone. Less fatiguing to listen to, I find myself listening to more music again these days.

The C45 isn’t better than the P7 on all counts but I would say it is a better choice for me. It fixes most of the CONS from the P7 and only bring a few steps down. Volume change is smooth, unused inputs can be turned off, 2 inputs can have 2/6ch modes, etc.

CONS:
1/ No tape out 6ch down mix (McIntosh confirmed that would have added audio processing that was not part of the design)
2/ Input names can’t be change (so... my BD player is officially "DVD" !)
3/ Trim can be adjusted from the remote, but not bass/treble.
4/ Trim by-pass is not available on the remote.
4/ Display can’t be turned off completely but it can be dimmed to low levels
5/ The plastic used for the original remote control (HR071) basically melted over the years. The replacement (HR093) is great but cost another $200.

PROS:
1/ Sound is definitely better to my ears
2/ Unused inputs can be turned off
3/ Front can be bi-amped (C45 has a pair of RF and LF)
4/ I does look good with its glowing green LED/fiber display ;-)
5/ Dead quiet, no humming on speaker at any volume
6/ Softer switch from sources (there is a temporary volume down/up to make it sound comfortable, the P7 would switch right away)
7/ The POWER control to the amp works and this time the lights remain on and can be adjusted with the knob.
8/ Phono sounds even better

So, as a conclusion, I would not recommend the P7 for a full audio setup but only for smaller satellite speakers that would be driven from a DVD/BD player with multi-channel outputs + few other sources. For a heavier setup, I don’t think it delivers the "neutral" sound I read about and actually degraded my mids quite noticeably.

Did anyone ever played with a P7 <=> C45 before?
