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.
I certainly wouldn't buy an active preamp before I'd tried one and compared. Your CD player may/may not be up to going it alone, you may/may not value transparency more than what you get (maybe euphonic) with an active preamp. I sold a CAT SL-1 III and went passive because of what I valued more, but don't assume that my preferences will be shared. See if some friendly dealer will let you give an active preamp a try. And on the cables, many if not most would say that the most important IC is the one joining preamp to power amp.
Hello There!
Thought I'd give you my thoughts since I am i n a similar situation. I have a Levinson 39 going directly in to my Conrad Johnson Premier 11A. Simple, Elegant, sounds great.
The real issue lies in where the volume attenuation occurs in your CD player. In the 39 it takes place in the analogue
domain , not in the digital domain. Based on my limited research, this was critical to not losing resolution/quality
etc etc and I believe the product literature on the 39 did a good job of explaining how and why. I think its available on levinsons' web site.

By adding a preamp with no other swithching needs all you are accomplishing is another means of adjusting the volume while adding two more links to the playback chain, preamp and interconnects.Though I am not a big believer in all the babble surrounding interconnects which seems completely unverifiable, unless YOU can actually hear the difference, I do believe a system is only as goood as the weakest link in the chain, which follows the same reasoning that simpler is better. With this in mind I would think that ifyou are planning on remaining a one source input kind of guy, your preamp dollars would be better spent on improving either your amplifier or speakers or both. This assumes your unit's volume control works within the analog domain and is not compromising quality with a digital volume control.

I've got almost 18 grand in my system and I auditioned a Linn Classic all in one cd amp with a pair of small revel monitors at 2000 a pair and I'd swear it got 95%
of the performance of my system for 20% of the price. Bottom Line is, if you like what you have who cares what the people with more money than brains have? I wanted a Premier 14 preamp because of all the great reviews etc etc but anytime I asked myself what I was getting for 3-4000$ the only answer I came up with was another box. What would improve my system would be more power for the signature 30's. Good Luck and Good Listening!

Thanks for your input guys. I now have a few more questions...

Genesis168:
Why is it preferable to have a lower output impedence interfacing the amp?

Tom Nice:
I'm a little unclear on what it is you are saying - partly, no doubt, because I don't know what you mean by passive/active preamps...

How do I tell if my volume control is digital or analog? I assume it's analog since it's an actual knob on the front of the player which controls both headphone jack and the variable output jacks on the back. Also, it's not controlable via the remote.

Thanks,
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!
