pre-amp suggestions

Hello folks,

currently I have two amps and one headphone amp that I am using as pre-amp, as it has this option. I am looking for decent pre-amp (used) that I can get in Canada for around 400$. I will list bellow my amps and what I was thinking of in terms of getting it...

1. Rotel RB-1050 - http://www.rotel.com/en-ca/product/rb-1050
2. Rotel RB-1562 - http://www.rotel.com/en-ca/product/rb-1562

Current headphone amp running as pre-amp: ASL or Antique Sound Lab MG OTL 32 DT ( http://www.divertech.com/aslmgheadotl32.html )

I was looking into the following:
Parasound Halo P3 - https://www.parasound.com/vintage/p3.php
Emotiva USP-1 - https://www.amazon.ca/Emotiva-USP-1-.../dp/B008O37FXA

The power amps are connected to following speakers:
1. PSB GB1 - http://www.psbspeakers.com/products/...-GB1-Bookshelf
2. Wharfedale 220 - http://www.wharfedale.co.uk/diamond-220/ + Wharfedale D10 - http://www.wharfedale.co.uk/wh-d10/

I will add later on another sub to pair with PSB GB1 but for now need pre-amp while I will have two systems running, one at house and another at condo.
Please note that those Rotel amps are sounding very different when ASL was run as pre-amp.

Thanks!

Depends on what you like. You're running a tube preamp, so of course the amps will sound "very different". If you want solid state, you might try to hunt up a used Rotel RC-995 preamp, which is all the preamp most 2-channel rigs would ever need. Especially since it has two sets of unbalanced outputs, allowing you to run a subwoofer. (It has one set of balanced outputs, but they can't be run at the same time as the unbalanced, eliminating the subwoofer option.)



But if you really want tubes, you'll have to look elsewhere. I would want to see the specs on the ASL.

The specifications for ASL should be on the link provided...
I was looking for solid state preamp while the ASL will get designated tube power amp or Moscode 600 and that’s the reason I picked those pre amps mentioned in original post.

Maybe I had overlooked something but prefer to have some kind of sub management.
The other option is to get vintage solid state pre amp from 80’s or 90’s like Teac or Yamaha, Sony ES or similar with double outputs for sub.

Any idea what will pair good with those Rotel amps?
Also, how sounds Halo 3 and Emotiva pre amps?

Thanks!


EDIT: That Rotel RC995 is a good choice but need to find one... I found RC-1070 locally though.

$400 is tough but the Parasound zpre3 is what I’m thinking you mean? I’d go with that myself.

Not really. There is plenty of pre-amps (used) available locally. Both I have mention in original post, Halo 3 and Emotiva, are around that price +/- 100$...

I've owned the USP-1 for a time. It is quite transparent, easy to operate, and has a crude but effective bass management system for 2 channel as long as you aren't looking to use it in a home theater bypass setup, which it sounds like you won't be doing.

It will be just 2.1 audio set-up... Can you shed more light on the sound and to what is comparable?

P.S. For home theater I will have just basic HT receiver and I guess I have my mind already set on Sony DN1080 with Canton HT speakers (for condo) and for the house maybe the same or DN1060 with Tannoy HT speakers. Have already both speaker set's.

I don't get into the nuances of this or that preamp, amp, etc. It either sounded good, or it didn't. The USP-1 sounded good. Whatever you put into it is not altered from what I could tell. And the phono section was quite good for an inexpensive preamp. I believe it is the same as in Emotiva's XSP-1 phono section, and I've owned one of those as well. I've also owned B&K preamps as well. I believe the 5000 you mentioned above is one of their AV series preamps, which I've never owned.

I think you mixed something here? I was talking about Parasound, Rotel and Emotiva only...

Just short update...

I got Rotel RC-1070 to go temporary with until I find Parasound 2100 V.2 or Halo P5, tending to go with P5, that will fit the price range I am looking for.
Also I am keeping an eye on Rotel RC-1580 or RC-1590... have to do more research into those.

The RC-1070 plays very good with RB-1050. This combo is really recommended to anyone but be aware that on some speakers some might find that it is on the brighter sounding side. Other then that I just shortly connected a turntable what I am currently selling, just to test, and I was amazed at phono stage this pre-amp offers. It is excellent, worth alone the price of the pre-amp.

Thanks for help folks!

I owned a Parasound P5 while my Emotiva XSP-1 was being repaired. With the P5, the volume control range all happens at once between the 7 and 9 o'clock positions so very difficult to set. Also found it degrades the sound, sound stage is flattened and detail is lost. But other people might be quite happy with the P5.

Thanks, for letting me know. In the mean time I changed my mind since having RC-1070 and was thinking to abandon the idea to get P5 or 2100 V.2 and to stick with Rotel.
Your response contributed to that as well. I will be on the look out for Rotel RC-1580 and will get miniDSP instead off a pre-amp with integrated bass management.

BTW How is sonically XSP-1 vs P5, just curiosity? What was your impression, more detailed ie. what power amp did you use, etc.?

I have a bad idea to get as well used Rotel RB-1090 power amplifier later on, since they do not make them anymore...

Currently I have Rotel RB-1050 (I am the original owner) and I like it... I do have Rotel RB-1562 as well which to my surprise is really good for class D amp, if I dare to say excellent. I had experience with class D amps and did not like most of them but this one, it might be a keeper...

My power amp is an Anthem MCA 50 with two channels used for the left and right and a third for an underfloor vibration transducer (I much prefer that to using a sub for music). My main source is an Oppo 105D. With the P5, the sound is like its coming from two point sources (the speakers) and sounds flat and recessed, whereas with the XMC-1, the whole front wall seems like a giant speaker and the sound comes out into the room, very engaging. With the P5, I just didn't want to play music any more. Even the wife asked what happened to the sound when the P5 was in use. Tonally, they both sounded the same, but perhaps the P5 sounded a bit harder.

I'm a hardware engineer by trade and even I can't think how the differences I described could be measured. The P5 was just sucking the life out of the music. Its gain seemed ridiculously high so perhaps having the volume control way down towards zero was part of it.

But who knows, in a different room and with different source and power amp, the P5 might sound perfectly fine.
