Preamps waste of money?

Preamp has many functions other than volume control
- input selector
- balance control (some have tone control)
- impedance matching
- allows use of balanced cables
- breaks ground loops on balanced connections (transformers)
- absolute phase inversion
- some allow to adjust level for each input (Rowland Chorus)
- have unity gain bypass for the theater system
- phono amp for TT
- rumble high pass filter
- remote control
etc.

If you don't need any of it then any stand alone volume control will do. I use Benchmark DAC1 as a preamp with volume control for 3 digital sources with balanced cables to power amp.

Brighter sound of SS amps is related to Transient Intermodulation distortion (TIM) caused by negative feedback used to linearize output transistors especially in class AB amplifiers. Product of TIM is overshoot of transitions (in time domain) equivalent of producing odd order harmonics (in frequency domain). On the other hand overly warm gear, that might sound great on guitar or voice, can make other instruments with complex harmonic structure sound wrong. For instance piano, that has harmonics much more complex than simple overtones, can sound almost "out of tune". Ideal amp shouldn't add anything of its own, IMHO, pleasant or not.

Dracule1, Hyperions are really sad story. Company had absolutely great innovative product with many awards to practically fold the business down. They had poor dealership base, poor customer support, no marketing etc. I was lucky to still get it. With neutral sounding class D amp (Rowland 102) it is a little on the warm side but it sounds great even on lean/bright records. I need a little more highs (air) but it might be room acoustics (reverberation) or class D limitation. Midrange is to die for while bass is tuneful with very realistic attack and decay.
