To Preamp or not to Preamp, that is my q


To Preamp or not to Preamp, that is my question. I have a Denon DCD-1650AR which is connected directly to a Parasound HCA-2200II via Maple Audio Ambiance interconnects. Yeah, I know, low-end gear compared to most of you guys, but it sounds pretty good to me...

My intent was (and is) to keep it as simple as possible and assumed that the more direct the path and the fewer components, the more "honest" the sound reproduction would be. As I say, it does sound very good to me. But could it sound better with the addition of a quality preamp? One other related question: Adding a Preamp obviously require another set of interconnects. Do the ones between the preamp and amp need to be of the same quality as used between the player and the preamp?

In your responses, keep in mind my minimalist philosophy. I would consider adding a decent quality preamp, but I am not interested in upgrading the player, separating it to transport/DAC etc. Simple is better for me. I have no other sources, so do not need any switching capability.

Kind regards...

Preamp! It acts like a buffer stage to drive your cables. The output impedence on a preamp is far lower than a CD player. That's why you need one.
Hin Levinson 39 has a preamp section built in it. That's OK to connect to a power amp. 99% of other CD players like the Denon used here does not have one built in.

To use a regular CDP as a drive for power amps are not appropriate. Sometimes getting a passive will do a great job but not always as some interconnects have higher capacitance values therefore cable matching is sometimes a problem without a preamp or with a passive.

Lower output impedence a preamp produces makes driving a cable easier therefore you will not suffer uneven frequency response. Sometimes w/ a passive, you will get rolled off highs and low frequency if the interconnect mismatch.

Well, as others have said, there is no right or wrong. If you think your system sounds great, then that be it. Save the money and buy yourself more music to enjoy.

Cheers!
In your situation, a pssive would only make the sound worse as there is a volume control there already on the CDP.

If you're into ultimate transparency in the sound, no preamp is the best way. Using a preamp would help make your music sound fuller and a lot more "EFFORTLESS". Yes, you might slightly lose some drgree of transaprency. Music is not always about transaprency as you don't hear is in live music. It's about everything else too....dynamics, immediacy, soundstaging, liquidity, etc. A good preamp might just help you get that.

Many of today's preamp do not add gain. They attenuate the CDP's output until the maximum level before gain is applied. They only act as a buffer to drive your cables. Likes the newer Audio Research's and the Levinsons, you'll get less sonic colorations. For sure there will be colorations but not too much.
