Audio research or Manley 300B pre amp for Upgrade


Dear: my respected fellow audiogon members,

After deciding on my speaker upgrade, I am now about to seek some improvement in my audio system. As currently using audio aero capitole mk2 source conected directly to my manley snapper monoblock, I was advised by some friends that I should instead add a Pre amp. However, as I read through some of other members discussion, I found out that there were pros and cons regarding the pre amp usage after the aero. Some opinions hold it strong against pre amp addition as it will alter the purity of signal coming out of the aero, whereas some others believe that by adding pre amp there will be more body to the music as well as depth and staging width improvement.

Now, that I have the choice to tryout for a pre amp, should I go for the Audio research pre such as ls27 or even the reference 5, or should I go simpler by using the single ended manley neo-classic 300B pre amp (which doesn't have the XLR connection).. I lean towards all genre of musics (country, jazz, classical, soft rock) with exception of hard musics..

Would anyone share with me some great expertise and wisdoms.. Thanks all..

Dear: musicophile and efner (and montejay too)

Thanks for the great advise, my only concern with the 300B neoclassic pre is that it doesn't have the xlr connection compared to the ARC. Would that single ended connection be a downside or instead a benefit in that sinergy?.. I want my music to come alive with good body and speed.. Of course with sweetness as well..I was told by a friend, the single ended connection is going to be sweeter whilst the xlr will give me more speed, transient, body and attack..does this concern you guys at all?. ..
Efner: I appreciate your elaborated answer.

Jonathan: RCA connection between preamp and Snapper doesn't concern me, as it doesn't concern Manley: they designed Snapper differentially balanced but their preamps single-ended because they think that works best together. You can send EveAnna or Chris at Manley an e-mail about the topic: they can give you the reasons why they designed it this way. Anyway, the synergy between Neo-Classic and Snapper is just awesome. Just think about it; an incredible idea - driving EL34 by 300B. And it works magic. Just my subjectivistic opinion and experience.
Dear: musicophile

Thank you for your great and valuable advise.. I will give it a try, and see how it works, I think, I will agree with your lead.. Have a great weekend..
Jonathan: Let us know about your decision and impressions.

I have faith in the importance of a preamp. I write "faith" because I can't back it up technically. However, listening has consistently given me the impression that a preamp influence the musical gestalt, especially dynamics, body and timbre. For me these are more important dimensions than transparency.
Jonathan,
The Coincident Statement linestage is simply outstanding! Montejay is correct in his description. However if for you it comes down to either the Manley or the Audio Research, given your system and preferences I`d select the Manley preamp in a heartbeat.
Best of Luck,
