Please recommend a PreAmp for my 5.1 home theatre system


I am putting together a system - so far have Krell Chorus 5200 for the Amp, and Focal Sopra No 2 speakers, along with Sopra center and Aria rear channels.  Samsung TV mid range M series.  Can you suggest a nice preAmp to work well for this system.  Budget 4 k tops.   Thanks!

how about a used Krell Foundation ?
McIntosh MX151 control center :-)   Ultimate for HT.


In my HT system I use an Oppo UDP-205 to do the processing, feeding the fixed analog 5.1 output into a Krell HTS 7.1. Audio processing in the Oppo is superb and the Krell is just acting as a glorified 5.1 volume control. Works perfectly for me and the cost of a new Oppo UDP-205 and used Krell HTS 7.1 is about half your budget.
The Oppo does have a volume control so you do not even need a pre amp.
Thanks for some great responses!  The OPPO idea is intriguing.  Didnt realize that a Blu Ray could double duty as a PreAmp.
you shouldn't use the Oppo to do the volume control duties... that said the Oppo205 is great for everything else.. I have one and had it modded (Modwright).. for music - analog out to HT bypass and for movies HDMI out..  Foundation perfect match for your amp
There is no problem using the Oppo's volume control. Once upon a time digital volume ocntrols were not a good idea as it cost you bit depth. These days, with internal 32 bit processing, this no longer applies. See here for a presentation by Sabre: http://images.computeraudiophile.com/graphics/2015/1216/digital-vs-analog-volume-control.pdf
Why not? There is no technical reason not to use the volume control on the analogue outputs. Just look a that Sabre presentation. Times have changed.
I suggest an Anthem AVM-60. I think it is $3K new and can sometimes be found here used. Importantly, it has ARC built in, which is fairly easy to use, and can make a dramatic improvement in SQ especially in rooms that are not acoustically treated. I don't know how it will match with your amp, but I run mine with an Oppo 205 as a source. It provides a terrific home theater experience in a very large room.
Happy hunting

on paper it looks ok... but ask Oppo and they'll tell you for best results, its better to use a preamp for the volume control...... know that all volume controls does some harm to the signal.. its just that some does less harm than others.. analog seems to work the best thats why you see higher end preamps/processors incorporate an analog volume control into their all digital preamps.. My Classe SSP800 has an analog volume control for example..  there's many different designs in volume control, each one trying to better the other.. PS Audio claims they make the best one yet
Another vote for the Anthem AVM 60. Nice unit for both h/t and 2 channel.

For digital vs analogue volume control, I simply repeat the reference to the Sabre presentation (there is also a longer text by Sabre but I could not quickly find it). Can you hear imperfections at -135dB, and do you have source material that is this clean? Do not forget that analogue volume controls have their weakneses as well, like channel imbalance at lower levels. There are more important things to worry about.

like I said (actually repeating what the manufacturers say), all volume control does some harm.. pick what works best for you..

willemj, does that test include turning up the volume across 6 channels for surround sound or just stereo ?

Hi, I also have the Focal Sopra 2, Focal Chorus surrounds and am waiting for the Focal Sopra Center to arrive this week. I am using Marantz 8801 as a preamp/pocessor and am extremely happy with it.
I have tried using the Oppo 95 as a preamp before buying the Marantz and the Focals, but the sound was horrible so I would definitely recommend using a real processor.
