OK...I'm getting ready to buy a new Phono pre amp.


.........but......should I consider buying a new pre-amp first???? How about upgrading my TT???
I am very interested in replacing my ARC PH3 SE with a the Aesthetix Rhea. However, before I do that, do I replace my ARC LS 25 mkl with...the Calypso?? Then, maybe replace my Aries with the new VPI TNT X HR? I don't want to do this all at once so your advice would be helpful. Thanks all!

Hi Rwd: I think that is not a very good idea to buy the phono preamp that Topoxforddoc told you. I explain why:
- first: both units ( Comet and meteor ) are an outboard phono stage, so the signal has to goes trough additionals cables and connectors that degraded the critical signal that comes from your MC cartridge. - Second: Both units use ( internally ) transformers for achieve the gain for a MC cartridges, so here the signal again has to be degraded for many meters of wire in the transformer where the signal has to goes and- Third ( not last ): maybe the most critical issue in the analog sound reproduction: the RIAA frecuency response of those units; a good phono preamp design ( with a good execution of that design ) has to have a RIAA frecuency response of at least: +,- 0.1 db from
20Hz to 20,000 Khz. Those units has a deviation of ten times ( 1 db at 20Hz ) over this RIAA response, this number is by a high-end standard: inaceptable.
Once ( maybe still today ) the Vendetta Research was the standard, it has a RIAA frecuency response deviation from 20Hz to 20,000 Khz of only: 0.05 db, I think the FM Acoustic preamp meets this number, too. I'm not a man of electronic specifications but in the phono stage the RIAA frecuency response is extremly critical and no one has to leave " pass-on ".
BTW, I give you my advice: first change your phono cartridge ( trying to match with your tonearm ) for a better one and a second step will be to change your preamp for a new one that has a high gain ( depends of the phono cartridge ) buil-in phono stage ( with out transformers ).
Regards and always enjoy the music.

Rwd- I also am of the opinion that you already have good stuff.I personally would keep the PH3SE and look at finding a different cart first. Perhaps something that matches up better with the VPI JMW better. It seems to do better with the higher compliance cart around 15cu..like the Dynavector 17d2Mk2. Then you can add a high quality step up transformer like the Bent Audio MU( $775.00) (www.bentaudio.com.) which will also let you vary the load for the cart you choose. In this way you will optimize your playback and bring more life and dynamics to your music. This is the route I choose and am very happy with my Aries/JMW/ Dynavector and PH3 SE. Not saying you should not change anything like pre amp or table..but I would try to get the most of what you have also.. The suggestion of the simple tube swap is avalid idea also..The ARC's will respond nicely to something like the Siemens 7308's or Amperex BB 6DJ8's. Good luck!- Ken
In response to Raul,
1. the Tron preamps are now available as a one box item as opposed to a separate line stage and phono stage.
2. there is a lot to be said for transformers providing they are of high quality and shielded correctly
3. remember you should use your ears when evaluating equipment. I used to sell hi-fi with Ken Kessler - before he became a critic and I became a surgeon. I know what I like - that's live music. The Trons go a long way to getting there. They're also supremely quiet - not only for a tube preamp, but also as quiet as a good solid state set up! You don't believe me - then have a listen.
Thanks all...wow. Many suggestions! First off, I also have a Benz M2 cartridge besides the Helikon. However, what (besides the Dynavector) would be recommended? I was actually considering a London Decca or a Koetsu.

How about that? And I must confess to all...I placed my order for the Rhea. But I would love to hear more!!!
Rwd, congratulations on you decision to order the Rhea. I hope you will enjoy it as much as I enjoy the Io; its a beautiful phono stage.

The Calyspo will give you another improvement in sound quality, but you may want to live with you new Rhea phono stage for a while and think about what changes to your system will really improve the sound you want to achieve relative to your listening priorities. Your system will be at a very high level. Changes from here need to be matched carefully against your listening priorities and synergies with either (a) the rest of your system or (b) your system as you want to have it evolve from here. I think the sound you will get from the Rhea may lead you to consider some directions you might not currently contemplate.

Best wishes,
